IMPROVEMENT ON DIRECT MODULATION RESPONSES AND STABILITY BY PARTIALLY CORRUGATED GRATINGS BASED DFB LASERS WITH PASSIVE FEEDBACK

Improvement on Direct Modulation Responses and Stability by Partially Corrugated Gratings Based DFB Lasers With Passive Feedback

DFB lasers with ultrashort cavities or integrated DFB lasers with passive waveguide reflectors are frequently proposed to realize directly modulated lasers (DMLs) for carrying ultrahigh data rate signals.The former suffers from poor heatsink and laser cleavage yield, while the single-mode stability of the latter scheme is seldom addressed.The mode
