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…
Saturable absorption in defect-rich diamond nanophotonics
Christopher Coutts, Nicholas J. Sorensen, Elham Zohari +3
Diamond is a leading quantum photonics platform due to its ability to host qubits based on crystal defects such as nitrogen-vacancy centres. Fabricating nanophotonic devices from d…
Selective Single and Double-Mode Quantum Limited Amplifier
Abdul Mohamed, Elham Zohari, Jarryd J. Pla +2
A quantum-limited amplifier enables the amplification of weak signals while introducing minimal noise dictated by the principles of quantum mechanics. These amplifiers serve a broa…
Nanoscale Torsional Optomechanics
P. H. Kim, C. Doolin, B. D. Hauer +4
Optomechanical transduction is demonstrated for nanoscale torsional resonators evanescently coupled to optical microdisk whispering gallery mode resonators. The on-chip, integrated…
