AlGaInAs/InP EML with Sidewall Grating Distributed Feedback Laser and Quantum Well Intermixing Technology

Abstract

An electro-absorption modulated laser comprising a sidewall grating DFB laser and quantum well intermixed electroabsorption modulator with 10 nm blueshift is modelled. An extinction ratio of 40 dB and −3-dB bandwidth of 17 GHz are derived at −2.5 V and −1.6 V EAM bias, respectively.
