Abstract
A 1.55μm multielectrode DFB laser, with both flat FM response characteristic and spectral linewidth as narrow as 4.5 MHz, has been fabricated by an MOVPE/LPE hybrid growth method. Since this device is relatively easy to fabricate, the multielectrode DFB laser is most promising as a coherent FSK transmission light sourceKeywords
