WDM operation of a hybrid emitter integrating a wide-bandwidthon-chip mirror

摘要

A wide-bandwidth on-chip mirror based on a deeply etched Braggngrating localized over 10 Μm is presented; it exhibits reflectivitynover more than 25 nm. Integration within a laser-Mach-Zehnder modulatornis shown and the wavelength-division multiplexing capability of thendevice demonstrated in a hybrid Bragg reflector configuration, bynshowing operation of the same InP chip with fiber gratings from 1534 ton1558 nm
