Abstract :
High-speed modulation with flat frequency response has been realized in an InGaAsP/InP DFB laser at 1.3- mu wavelength. The laser design uses an isolated narrow mesa and a novel air-bridge contact configuration. A direction current modulation bandwidth in excess of 17 GHz was measured.<>
