Suspended gallium arsenide platform for building large scale photonic integrated circuits: Passive devices
Pisu Jiang, Krishna C. Balram
The spectacular success of silicon-based photonic integrated circuits (PICs) in the past decade naturally begs the question of whether similar fabrication procedures can be applied…
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…
Single photon emission and single spin coherence of a nitrogen vacancy centre encapsulated in silicon nitride
Joe A. Smith, Jorge Monroy-Ruz, John G. Rarity +1
Finding the right material platform for engineering efficient photonic interfaces to solid state emitters has been a long-standing bottleneck for scaling up solid state quantum sys…
Microwave-to-optical transduction using a mechanical supermode for coupling piezoelectric and optomechanical resonators
Marcelo Wu, Emil Zeuthen, Krishna Coimbatore Balram +1
The successes of superconducting quantum circuits at local manipulation of quantum information and photonics technology at long-distance transmission of the same have spurred inter…
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…
