In this DURIP program, we have acquired the equipment to have assembled a versatile system for ultrafast optical and electrical modulation and excitation of semiconductor polaritons half-light half-matter particles in semiconductor microcavities, for the research of nonlinear and quantum photonic phenomena and novel photonics devices based on coherent matter-waves. The full system consists of three major parts that are integrated together cryogenic systems with custom-designed sample chambers and sample holders to allow optical access, electrical control, and required thermal and mechanical stability, an ultrafast electrical system with capability of ultrafast electrical excitations with 10 GHz bandwidth and less than 10 ps jitter, and an ultrafast pulsed optical excitation and detection system. The complete integrated system enables versatile excitation and measurement capabilities unavailable before at Michigan for the microcavity polariton based quantum photonics.
