DWDM Source Utilizing a 4PS-SBG DFB Laser Array with Monolithic ATG Technology

We report a 4-channel DWDM DFB laser array using four-phase-shifted sampled Bragg grating and asymmetric twin-waveguide technologies, achieving 0.873 nm spacing, >45 dB SMSR, and >10 dB electro-absorption modulator extinction ratio.
