Abstract

High-performance photonic integrated circuits require flexible yet robust integration platforms. In this paper, we discuss issues related to various integration platforms and techniques in InP used at UC Santa Barbara. These platforms include the traditional offset quantum well approach as well as novel integration methods using quantum well intermixing or dual quantum wells. Testing results of some of out latest devices are presented, including a tunable all-optical wavelength converter operating at 40 Gbps RZ, tunable Mach-Zehnder modulator transmitter operating at 40 Gbps NRZ, and a photocurrent-driven tunable wavelength converter operating at 10 Gbps NRZ.
