Acquisition Measurement System and Components for Development of Middle-IR Integrated Microwave Photonics

Abstract

We request funds from the DoD to: 1) upgrade our existing passive device measurement system to allow the operation wavelength cover 1 to 5 ?m, and 2) upgrade our existing high-frequency device measurement system to allow for systemic characterization of GeSn/SiGeSn near- and mid-infrared (NIR, MIR) modulators and high-speed high-power detectors up to 70 GHz. The newly upgrade components and built systems, include i) tunable lasers with wavelength coverage from 2 to 5 um as a mid-IR source, ii) optical spectrum analyzer to measure the output of integrated microwave photonic circuits, iii) custom-designed IR modulators and detectors, and iv) bit rate error tester and sampling oscilloscope to analyze the signal quality and error rate of the microwave photonic devices. We also plan to upgrade the existing nano piezo-positioners and fiber holder for better flexibility in handling IR I/O fibers. In addition, the current 40 GHz network analyzer will be upgraded to 70 GHz to boost the capability of the high-speed measurement setup. The new setup upgraded with the proposed instruments together with existing optical pumping, electroluminescence (EL) and Fourier transform infrared (FTIR) spectroscopy measurement systems (from our collaborator at University of Arkansas at Fayetteville) enable the research team to develop a complete set of components with light source, analog signal processing, light detection, and SiGe Radio-Frequency (RF) circuits all-in-one silicon platform to achieve high-performance low-cost mixed-signal optical links. Such research allows the research team to investigate the feasibility of obtaining a fully Integrated Microwave Photonics (IMWP) platform on a Si substrate. The requested instruments in this proposal will provide a unique setup at UAPB for characterization of mid-IR high-speed integrated microwave photonic devices.
