Mode locked and distributed feedback silicon evanescent lasers

Electrically pumped lasers that can be made on silicon and integrated with other components are important in order to take full advantage of the capabilities of silicon photonics. In this paper we review two speciﬁc types of hybrid silicon evanescent lasers that can fulﬁll these requirements. We discuss recent results of distributed feedback(DFB) lasers and mode locked lasers made on silicon using evanescent coupling to thin ﬁlms of III-V material. Device designs and test results are discussed in detail.
