The increase of device lifetime and reliability of THz photomixers will play an essential role in their possible future application. Therefore, their optimal work conditions/operation range, i.e., the maximal incident optical power should be experime

We present inverse-designed arrays of vertically-coupled, high-finesse, wavelength-scale photonic crystal cavities in a commercial foundry. Dynamically controlling each pixel with a high-speed (~100 MHz) µLED display enables efficient spatial light

We present a new architecture for performing learning-based tasks directly on an integrated photonic chip. We experimentally realize logical 2-bit gates AND, OR, and XOR to accuracies of 96.8%, 99%, and 98.5%, respectively.

We present a thermally isolated phase shifter through undercutting the silicon waveguide and resistive heaters, yielding a low-power (Pπ = 1.2 mW) and low-crosstalk tunable Mach-Zehnder interferometer.

As computing resource demands continue to escalate in the face of big data, cloud-connectivity and the internet of things, it has become imperative to develop new low-power, scalable architectures. Neuromorphic photonics, or photonic neural networks,

To investigate the viability of on-chip grating couplers as illuminators, we present a III-V detector illuminated with a bi-layer silicon nitride grating coupler. A responsivity of 0.233 A/W was obtained, corresponding to a measured fiber-to-detector
