Diamond optomechanical crystals for high-frequency strain and comb generation
Elham Zohari, Waleed El-Sayed, Aria Jafari +5
Quantum optomechanical technologies benefit from mechanical oscillators that are high-frequency, can be coherently driven, and are capable of coupling to other quantum systems. Dia…
Exceptional points in diamond optomechanics
Waleed El-Sayed, Elham Zohari, Joe Itoi +6
Multimode cavity optomechanical systems allow light to couple otherwise non-interacting mechanical resonators, enabling non-Hermitian phenomena such as exceptional points, where ei…
Large-amplitude diamond optomechanics by traversing a nonlinear attractor
Peyman Parsa, Waleed El-Sayed, Parisa Behjat +2
Nonlinear dynamics clamp the amplitude of mechanical resonators driven into self-oscillation by optomechanical backaction. Here we overcome the conventional limits of self-oscillat…
Photorefractive tuning seeded by third-harmonic light in a diamond photonic crystal cavity
Joe Itoi, Elham Zohari, Nicholas J. Sorensen +6
Single-crystal diamond nanocavities have tremendous potential for use in quantum and nonlinear optical technologies. The ability to precisely control their resonant frequencies is…
Double Etch Method for the Fabrication of Nanophotonic Devices from Van der Waals Materials
Otto Cranwell Schaeper, Lesley Spencer, Dominic Scognamiglio +8
The integration of van der Waals (vdW) materials into photonic devices has laid out a foundation for many new quantum and optoelectronic applications. Despite tremendous progress i…
