Arbitrary wavelength-range modulator-integrated DFB lasers on a single wafer for WDM applications

Abstract

Fabrication technique of modulator integrated DFB lasers with arbitrary wavelength range in a single wafer is proposed and demonstrated Devices with a wide wavelength range from 1530 nm to 161Onm were fatricated using four wafers. It was also confirmed wavelength range covered in a wafer could be arbitrary changed.

“…Stable wavelengths of DFB lasers are also required for wavelength division multiplexing (WDM) network systems [6][7][8]. Furthermore, uncooled, directly modulated DFB-LDS are one of the key devices for 10 GB/s Ethernet and OC-192 applications in recent years [9][10][11][12].…”
