Abstract
We report the design and performance of an InGaAsP/InP multiquantum well tunable distributed Bragg reflector optical intensity modulator module for wavelength division multiplexing systems operation near 1.55 micrometers . The module is composed of three wavelength-selective electrorefraction type modulators in tandem. The device presents for 1.54 micrometers an extinction ratio of 18.3 dB at 3.0 V and an insertion loss of 4.0 dB with 3.0 V applied to the other two modulators. Optical tuning of 5 angstrom is obtained with the application of 3.0 V to the Bragg reflector sections. The modulation and tuning bandwidth of 30 and 14 GHz is predicted for a modulator length of 220 micrometers . The total module length is only 675 micrometers .
