42 GHz bandwidth InGaAlAs/InP electro absorption modulator with sub-volt modulation drive capability in a 50 nm spectral range
31 May 2004
By enhancing excitonic absorption in a new design of a polarization independent EA modulator, a 50 nm flat absorption spectrum, 42 GHz bandwidth devices together with 14-30 dB/V modulation sensitivity are obtained for 75 μm long devices.
