780 nm Distributed Feedback Lasers with a Lateral Modulated Four-Phase-Shifted Sampling Grating
Year: 2024
Type: conference-paper
Abstract: A 780 nm distributed feedback (DFB) laser employing a four-phase shift sample grating and lateral modulated four-phase-shifted (LM-4PS) grating was successfully showcased. The LM-4PS effectively suppressed the longitudinal spatial hole-burning (SHB) effect, ensuring stable single longitudinal mode operation over an extensive range of operating currents.
