Abstract :
Summary form only given. It is very difficult to realize low distortion (DFB-LDs) distributed Bragg reflector laser diodes with high yield, although there have been many efforts to improve the linearity of L-I characteristics. The modulation distortion of DFB-LD is mainly caused by 1) spatial hole burning (SHB), 2) leakage current, and 3) intrinsic nonlinear response. In particular, 3) is the serious problem which prevents achieving the high speed analog transmission. Here we report approaches to the low distortion and low noise DFB-LD for high speed analog applications
