Multi-Wavelength DFB Laser Based on Sidewall Third Order Four Phase-Shifted Sampled Bragg Grating with Uniform Wavelength Spacing
Xiao Sun, Zhibo Li, Yizhe Fan +5
We present the first demonstration of a 1550 nm multi-wavelength distributed feedback (MW-DFB) laser employing a third-order, four-phase-shifted sampled sidewall grating. By utiliz…
Widely Tunable Photonic Filter Based on Equivalent Chirped Four-Phase-Shifted Sampled Bragg Gratings
Simeng Zhu, Bocheng Yuan, Mohanad Al-Rubaiee +6
We have developed an integrated dual-band photonic filter (PF) utilizing equivalent chirped four-phase-shifted sidewall-sampled Bragg gratings (4PS-SBG) on a silicon-on-insulator (…
Continuous Phase Modulation Technology Based on Grating Period Interval for High Grating Coupling Efficiency and Precise Wavelength Control
Yiming Sun, Simeng Zhu, Bocheng Yuan +6
A novel grating modulation technique for laser arrays is proposed and demonstrated. This method modifies the initial phase within each grating period, applying a total phase shift…
Narrow Linewidth Distributed Feedback Lasers Utilizing Distributed Phase Shift
Yiming Sun, Bocheng Yuan, Xiao Sun +6
This study proposes and experimentally demonstrates a distributed feedback (DFB) laser with a distributed phase shift (DPS) region at the center of the DFB cavity. By modeling the…
