Utilizations of fiber Bragg gratings and Fabry-Perot lasers for fast wavelength switching technique

Abstract

A novel tunable laser structure, based on Fabry-Perot lasers and fiber Bragg gratings with self-seeding operation, is proposed and experimentally investigated. The wavelength tuning can be obtained by properly adjusting the bias currents of FP lasers. The response time of wavelength switching of < 6.8 ns, a 3.38 mn tuning range, and a side-mode suppression ratio of > 23 dB have been achieved experimentally, This proposed tunable laser has the advantages of simple architecture, potentially low cost, data direct modulation and fast wavelength switching.
