Abstract
We present a 1.53μ m electroabsorption modulated distributed feedback laser (EML) fabricated by ion-implantation induced quantum well intermixing (QWI) with etching implant buffer layer. This simple QWI technique can suppress band-edge shift of laser region. The EML exhibits a 18dB@-5 V DC extinction ratio.
