Quasibound states in the continuum in photonic-crystal-based optomechanical microcavities
Cindy Péralle, Sushanth Kini Manjeshwar, Anastasiia Ciers +2
We present a detailed study of mechanically compliant, photonic-crystal-based microcavities featuring a quasi-bound state in the continuum. Such systems have recently been predicte…
Integrated microcavity optomechanics with a suspended photonic crystal mirror above a distributed Bragg reflector
Sushanth Kini Manjeshwar, Anastasiia Ciers, Juliette Monsel +5
Increasing the interaction between light and mechanical resonators is an ongoing endeavor in the field of cavity optomechanics. Optical microcavities allow for boosting the interac…
Deep neural networks for the prediction of the optical properties and the free-form inverse design of metamaterials
Timo Gahlmann, Philippe Tassin
Many phenomena in physics, including light, water waves, and sound, are described by wave equations. Given their coefficients, wave equations can be solved to high accuracy, but th…
Cavity Optomechanics with Photonic Bound States in the Continuum
Jamie M. Fitzgerald, Sushanth Kini Manjeshwar, Witlef Wieczorek +1
We propose a versatile, free-space cavity optomechanics platform built from two photonic crystal membranes, one of which is freely suspended, and designed to form a microcavity les…
Suspended photonic crystal membranes in AlGaAs heterostructures for integrated multi-element optomechanics
Sushanth Kini Manjeshwar, Karim Elkhouly, Jamie M. Fitzgerald +6
We present high-reflectivity mechanical resonators fabricated from AlGaAs heterostructures for use in free-space optical cavities operating in the telecom wavelength regime. The me…
Anomalous optical saturation of low-energy Dirac states in graphene and its implication for nonlinear optics
Behrooz Semnani, Roland Jago, Safieddin Safavi-Naeini +3
We reveal that optical saturation of the low-energy states takes place in graphene for arbitrarily weak electromagnetic fields. This effect originates from the diverging field-indu…
