NEW PRINCIPLE = PHOTONIC MEMORY

NEW PRINCIPLE = PHOTONIC MEMORY = ANALOG MEMORYSCREEN -> LASER + WHITE LIGHT -> DISC -> CAMERA -> PHOTONIC MEMORYANALOG PRINCIPLE AND READING - INFORMATION QUANTA - REALITY AS WAVEReality records photo and video as light directly as light wave or for silicon as electromagnetic wave. Disc stores quanta of information. Photo and video are not bits, they are waves. Principle is analog.ANALOG PRINCIPLEAnalog not digital. Digital samples wave and stores 0/1 projection with quantization noise. Analog stores wave itself continuously. Principle stores reality as wave. Photo is wave frozen at time t0. Video is sequence of waves Q(t). Disc stores wave directly as volumetric grating. No digitization at storage. No compression artifact. Wave stored as refractive index modulation n(x,y,z).Reality emits light. Light carries quanta. Quanta is wave packet with amplitude A, phase phi, angle theta, wavelength lambda, polarization p, time t. Screen shows quanta or real object itself emits quanta. Laser creates interference in volume of disc. Interference is analog recording of wavefront. White light reconstructs analog wave. Camera reads analog wave. For photonic memory wave stays light wave all way to processor. For silicon memory wave converted to electromagnetic wave in circuit but still analog at storage stage before ADC. Both benefit from same disc.Photo example: doll front view is one quanta. Doll emits light wave Qdollfront = A(x,y,t) _ exp(i phi). Disc records Q. White light reconstructs same wave. Eye or camera sees doll as if real object present. Apple red is spectral quanta. Apple green is different spectral quanta.Video example: sequence of quanta Q1(t1) doll front, Q2(t2) doll side, Q3(t3) apple. Disc stores each quanta at different angle/phase/wavelength. Video is angle scan or phase scan. Reading white light scanning angles reproduces video as sequential wave reconstruction. Eye sees continuous motion.INFORMATION QUANTAQuanta of information = minimal distinguishable wave packet carrying reality. Not bit. Bit is threshold. Quanta contains image, depth, parallax, color, motion, phase, occlusion.Types:Spatial quanta: doll shape, apple shape as wavefront A(x,y). Each point has amplitude.Angular quanta: same object from different angle. #1 front, #2 side are different angular quanta of same doll. Parallax is angular quanta difference.Spectral quanta: same object at different wavelength. Red apple vs green apple vs blue apple. Each wavelength independent.Polarization quanta: H vs V polarization. Same object different polarization state.Temporal quanta: same object at different time. Video frame t1, t2, t3. Motion is temporal quanta sequence.Phase quanta: same object with different phase profile. Phase carries depth.Each quanta independent channel in disc. One disc holds millions of quanta. One quanta can be photo, video frame, data page.RECORD AS LIGHT WAVEPipeline for light wave:Real object or SCREEN -> object wave Wo = Ao exp(i phi_o)Laser -> reference wave Wr = Ar exp(i phi_r)Inside disc volume: interference I = |Wo + Wr|^2 = Ao^2 + Ar^2 + 2 Ao Ar cos(phio - phir)Photopolymer records I as refractive index n = n0 + deltan cos(K·r) where K is grating vector K = ko - kr. K carries analog info. Thick volume records K in 3D with depth.For silicon electromagnetic wave: same disc, after camera wave converted to voltage V ~ Eoptical. For silicon storage before ADC, electromagnetic wave in wire still analog: V(t)=Aem exp(i phi_em). Disc principle same, only final transduction differs. Light stores light, for silicon light converts to EM wave after reading. Recording stage identical.Screen example: screen shows doll pattern. Pattern diffracts laser. Wo created. Disc stores. Real object example: real doll illuminated by laser, scattered light is Wo. Real apple illuminated is Wo. Both record same way.Recording parameters analog: exposure energy 1-100 mJ/cm2, beam ratio 1:1 to 10:1, thickness 10 micron to 10mm, wavelength 405/532/633 nm, polarization matched.STOREVolumetric grating = analog photonic memory. Grating is continuous modulation, not discrete pits. Modulation depth deltan proportional to AoAr linearly. Therefore analog amplitude preserved linearly. No binary threshold.Storage analog density:Angle multiplexing: Bragg selectivity deltatheta ~ lambda / (T sin theta). T thickness 0.1-10mm. For T=1mm, lambda=532nm, selectivity ∼0.03 deg. 1000 angles over 30 deg in same spot. Each angle is separate photo or video frame.Phase multiplexing: 0-2pi orthogonal phase codes, 100 codes via phase modulator.Wavelength multiplexing: delta_lambda ~ lambda^2 / (2 T). ∼0.1 nm selectivity. 100 wavelengths over 10 nm.Polarization: 2 orthogonal states.Shift: 10 micron shift multiplexing.Total analog channels = Nangle Nphase Nlambda Npol. Example 10001001002=20,000,000 quanta per spot. One physical disc = thousands virtual discs. Each virtual disc = quanta.Disc analog like vinyl but for light. Vinyl stores sound wave as groove depth analog. Disc stores light wave as index depth analog. Longevity photopolymer stable, no charge leakage, 50+ years dark, no power, archival, no cryostat.RECONSTRUCT AS LIGHT WAVEWhite light reconstruction is analog. White light contains continuum wavelengths and angles. Grating selects matching K that satisfies Bragg.Bragg condition: krecon + K = kobject. White light provides krecon continuum. Grating picks correct kobject. Result reconstructed wave Wo' ~ Ao exp(i phi_o). Same as original analog wave.Result: doll appears floating with depth, parallax, occlusion, specular highlight. Apple appears red volumetric with shading. No laser needed for reading. Frame with apple hologram shows white light reconstruction with phone flash or LED.White light erasure is analog bleach: uniform white light floods volume, erases modulation, resets n to n0. Rewritable analog like audio tape erasure. Exposure 100 mJ/cm2 white erases.READ - ANALOG FOR PHOTONIC AND FOR SILICONFor photonic computer: camera reads light wave directly. Photonic processor processes wave without conversion. Photonic memory to photonic processor all-optical analog link. Quanta stays light. Photonic chip waveguides carry same wave. No ADC.For silicon: camera converts light wave to electromagnetic wave. Sensor photon->electron->voltage. Voltage is electromagnetic wave carrying same analog quanta but in RF domain. Before sampling, voltage analog: V=G*Ao. Silicon can store this electromagnetic wave in analog capacitor or sample to digital. But disc storage before camera is still analog light wave. Even for silicon pipeline, disc stores analog.Reading modes analog:Eye direct analog: eye sees reconstructed wave.Camera direct: sensor captures intensity |Wo'|^2 analog image. Photo.Holographic camera: interferes Wo' with reference, extracts phase phi_o analog via fringe pattern. Depth.Time-resolved: high-speed camera captures Q(t) video as sequence of quanta at 1000 fps.Multi-angle: multiple cameras capture different theta simultaneously.Video reading: scanning white light angle continuously -> continuous reconstruction Q1->Q2->Q3. Eye sees video as analog wave sequence. Camera records video as analog electromagnetic wave sequence. For silicon, electromagnetic wave video V(t) directly.PHOTO AND VIDEO AS WAVEPhoto is single quanta Q(x,y). Disc stores one grating per photo. Reading one angle gives one photo wave. Photo is not file, it is wave.Video is sequence Q(x,y,t). Disc stores many gratings Q(t1) at angle1, Q(t2) at angle2, etc. Reading scanning angle gives video. Or photorefractive with dynamic response stores moving grating as video directly.Reality records photo and video only as light wave. Not as bits. Bits secondary representation for transmission. Primary is wave. Principle restores primary. Light stores light.Example photo: doll front static. Record at theta=0 deg. Read at theta=0 white light -> doll front photo wave.Example video: doll rotating. Record doll front at theta=0, doll 10deg at theta=0.1deg, doll 20deg at theta=0.2deg up to 360deg. Read scanning theta 0->36deg -> video rotating doll as light wave.Apple video: apple falling. Record apple height h1 at angle1, h2 at angle2, h3 at angle3. Read scanning -> falling apple wave video as light.For silicon: same wave converted to electromagnetic wave V(t) after camera. Video as EM wave in wire.DISC FORMS AND MATERIALSCD 120mm with 1mm photopolymer laminated. Card credit card size with photopolymer. Plate glass 10x10cm with dichromated gelatin.

Compact device housing.For photonic memory: camera output goes to photonic chip via fiber or free space. Photonic chip processes quanta.For silicon: camera output goes to coax as electromagnetic wave, then analog storage or ADC if needed. Both use same disc principle.On-chip integration: SLM microdisplay, VCSEL array, photopolymer patch, broadband LED, photodiode array. Single chip photonic memory.CORE IDEAAnalog principle: reality is wave. Memory must store wave. Photo is wave, video is wave sequence. Disc stores quanta of information as 3D volumetric grating. Screen or object provides quanta, laser records quanta in disc volume as interference, white light reconstructs quanta as light wave directly, camera reads quanta as light wave for photonic or as electromagnetic wave for silicon. By changing angle and phase store any photo and any video layer like CD-RW but volumetric and analog. No digital sampling at storage.Pipeline: SCREEN/REAL OBJECT -> LASER + WHITE LIGHT -> DISC -> CAMERA -> PHOTONIC MEMORY (light wave) / ELECTROMA
