Abstract :
A factor of ten improvement of modulation bandwidth, from 2 GHz to 20 GHz, is demonstrated using phase modulator monolithically integrated to a semiconductor amplifier and a widely-tunable SG-DBR (sampled-grating distributed Bragg reflector) laser. This is achieved by generating optical frequency modulation converted to intensity modulation in an optical ASE filter.
