Photonics with superior properties can be implemented in a variety of old (silicon, silicon nitride) and new (silicon carbide, diamond) photonic materials by combining state of the art photonics optimization techniques (photonics inverse design) with new fabrication approaches. In addition to making photonics more robust (e.g., to errors in fabrication and variation in temperature), more compact, and more efficient, this approach can also enable new functionalities. While in our early work we focused on inverse design and demonstration of individual photonic devices, our more recent work focused on scaling it to photonic integrated circuits fabricated in a commercial semiconductor foundry. We illustrate this with several examples, including optical interconnects based on a combination of mode and wavelength division multiplexing, diamond and silicon carbide photonic circuits.

Prof. Jelena Vuckovic is a Jensen Huang Professor in Global Leadership in the School of Engineering, a Professor of Electrical Engineering and by courtesy of Applied Physics at Stanford, where she leads the Nanoscale and Quantum Photonics Lab.

Prof Vuckovic’s Nanoscale and quantum photonics lab investigates optics and light manipulation at the nanoscale. Harnessing developments in the semiconductor industry, we engineer platforms that both probe fundamental science and hold promise for future information technologies.Of paramount interest is studying solid-state quantum emitters, such as quantum dots and defect centers in diamond, and their interactions with light.

This talk is part of an ongoing series of talks by US and Australian researchers presenting novel developments in condensed matter and cold atomic physics, enriching connections between the two physics communities. Co-presented by FLEET, Monash School of Physics and Astronomy, and the Joint Quantum Institute.
