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…
Feedback Enhanced Phonon Lasing of a Microwave Frequency Resonator
Peyman Parsa, Prasoon Kumar Shandilya, David P. Lake +2
The amplitude of self-oscillating mechanical resonators in cavity optomechanical systems is typically limited by nonlinearities arising from the cavity's finite optical bandwidth.…
Kerr-optomechanical spectroscopy of multimode diamond resonators
Parisa Behjat, Peyman Parsa, Natalia C. Carvalho +2
Diamond microdisk cavities play a key role in optomechanical and spin-optomechanical technologies. Previous optomechanical studies of these devices have focused exclusively on thei…
