Optical modulator

The electroabsorptive waveguide modulator provides high-speed, low-chirp optical modulation with up to 10-dB fiber-to-fiber gain. The unit consists of a multi-quantum-well electroabsorptive waveguide modulator integrated with a semiconductor optical amplifier. Angled-facet configuration and antireflection coating eliminate backreflection and feedback. Modulation bandwidth is to 20 GHz, and modulation contrast is from 10 to 30 dB. Operating temperature is -20 to +60C.
