Abstract [en]
Directly modulated lasers (DMLs) are widely employed in optical communications due to their significant advantages. This paper investigates a dual-κ partial corrugated grating distributed feedback (PCG-DFB) laser based on an identical active layer (IAL) structure. By introducing multiple photon-photon resonance (PPR) peaks, the -3 dB bandwidth is extended to 140 GHz. The results demonstrate that the dual-κ PCG-DFB effectively flattens the small-signal response, which is beneficial for high-speed large-signal transmission, compared to conventional single-κ PCG-DFB laser.
