| Abstract(in English) | An InP-based athermal in-phase and quadrature optical modulator (IQM) was demonstrated for the first time. A single-RF drive push-pull MZM with a simple coplanar waveguide (CPW) was fabricated by utilizing a (110)-oriented InP substrate in terms of the crystallographic orientation dependence of the electro-optic Pockels effect. The device exhibits a 3 dB-EO bandwidth of over 25 GHz, and 56-Gb/s × 2 QPSK modulation. The variation in Q-factor over the entire range (20- 80 ℃) is less than 1.0 dB. Furthermore, a polarization converter with a trapezoidal core and a polarization beam splitter/combiner, which are suitable for device integration, were also successfully demonstrated. The converter exhibited a polarization conversion ratio of over 98% (C-L band) and a polarization extinction ratio of 10 dB (C band) in the polarization splitter. |
