Gallium nitride phononic integrated circuits for future RF front-ends
Mahmut Bicer, Stefano Valle, Jacob Brown +2
Achieving monolithic integration of passive acoustic wave devices, in particular RF filters, with active devices such as RF amplifiers and switches, is the optimal solution to meet…
Cryogenic operation of MEMS-based suspended high overtone bulk acoustic wave resonators for microwave to optical signal transduction
Stefano Valle, Krishna C. Balram
Suspended high-overtone bulk acoustic wave resonators (HBARs) can serve as a viable optomechanical platform for efficient transduction of signals from the microwave to the optical…
High frequency guided mode resonances in mass-loaded, thin film gallium nitride surface acoustic wave devices
Stefano Valle, Manikant Singh, Martin Cryan +2
We demonstrate high-frequency (> 3 GHz), high quality factor radio frequency (RF) resonators in unreleased thin film gallium nitride (GaN) on sapphire and silicon carbide substrate…
High-frequency, resonant acousto-optic modulators fabricated in a MEMS foundry platform
Stefano Valle, Krishna C. Balram
We report the design and characterization of high frequency, resonant acousto-optic modulators (AOM) in a MEMS foundry process. The doubly-resonant cavity design, with short ($L{\s…
