May 11 (Mon) @ 12:30pm: "Quantum Photonics with III-V Integration," Joshua Castro, ECE PhD Defense

Location: Henley Hall (HH), Room 1010

Abstract

Integrated photonics is essential for scalable classical and quantum systems, enabling efficient, stable, compact, and high performance devices for sensing, communications, and quantum information processing. III-V semiconductor materials are particularly attractive due to their strong second and third order optical nonlinear susceptibilities, a direct bandgap, and a large index of refraction.

In this talk I discuss applications of III-V integration, with a focus on Aluminum gallium arsenide-on-insulator based devices for entangled photon pair generation, and heterogeneous gallium arsenide-on-silicon nitride mode hop free tunable laser capabilities.
