Research on Aluminum Nitride Electrooptic Sensing featured in Optica

As described in May in Optica 11, 714-723 (2024), by using a combined microwave resonance and optical resonance, we demonstrated a passive metal-free electrooptic microwave detector that circumvents the need for conducting antennas, electrodes or electrical amplification.  The device uses optical resonators made of deposited aluminum nitride thin films, one of very few CMOS-compatible electrooptic materials, making it an appealing choice for future large-scale photonic integration.
