Upgrade of the III-N Integrated Quantum Photonics Laboratory Instrumentation
Abstract
The PI Yuji Zhao s group at Arizona State University has recently carried out III-N integrated quantum photonics research under the support of ARO. For example, the PI has demonstrated low loss AlN waveguides, high quality factor AlN ring resonators, and has successfully observed supercontinuum generation through dispersive wave generation and second harmonic generation from AlN waveguides. These preliminary results have shown the high potential of III-N integrated photonics, which could lead to the worldÕs first optical frequency comb in the ultraviolet to visible (UV-vis) spectral region, a significant breakthrough in this research area. However, due to the current limitation of instruments in the PIÕs lab, the fabricated III-N integrated photonic devices cannot be comprehensively characterized and analyzed. An instrumentation acquisition is urgently needed to continue current ARO project and to enable future work on III-N integrated quantum photonics for DOD and ARO. The primary instrumentation acquisition includes a state-of-the-art UV-vis Photonics Characterization System (UPCS) and the associated lasers, detectors, filters, etc. The UPCS has two key components: a state-of-the-art tunable laser setup at UV-vis range, which includes phase-locked tunable lasers, single mode narrow linewidth tunable lasers, and detectors; and a supercontinuum coherence testing setup with a broadband light source, a few UV filters, and UV-vis beam splitters. Acquisition of the proposed UPCS will enable many new methods of characterizations, and greatly enhance our overall capabilities for on-going and future DOD programs in developing UV-vis optical combs and III-N integrated quantum photonic devices. The expanded testing capabilities will also enable research-related education by serving as a state-of-the-art platform for the training of graduate and undergraduate students. Although cost matching is not required, ASU has provided $40,000 to purchase a state-of-the-art optical spectrum analyzer from Yokogawa (not included in this budget), which serves as a basic building block in the proposed UPCS.
