Strongly Gain Coupled DFB Laser Monolithically Integrated with a Self Alignment Spot Size Converter

强增益耦合 DFB激光器单片集成自对准模式变换器(英文)

A new type strongly gain coupled (GC) DFB laser and a new type self alignment spot size converter (SA SSC) are proposed and successfully fabricated.The strongly GC DFB laser is monolithically integrated with the SA SSC with three step epitaxies.A high single mode yield and large side mode suppression ratio is obtained from the strongly GC DFB laser.A near circle far field pattern is obtained by using the SA SSC.
