Photonics Transitor Non linear

This work documents the proof of concept of an all-optical transistor constructed independently in a home environment using non-linear Nd:YVO₄ and Potassium Titanyl Phosphate (KTP) crystals extracted from low-cost commercial laser modules. The device operates based on an interference-driven switching mechanism intuitively theorized and designed by the author. The observed physical interaction is based on the optical phase shift induced by the intensity of a second light source within the crystals, which alters the interference pattern at the system's output. This visual experiment proves a functional concept for photonic logic gates without requiring a complex laboratory infrastructure. This work represents an independent research featuring an original theory designed by the author and its successful home-based experimental validation.
