Route to Chaos in Optomechanics [PDF]
Physical Review Letters, 2015 We establish the emergence of chaotic motion in optomechanical systems. Chaos appears at negative detuning for experimentally accessible values of the pump power and other system parameters. We describe the sequence of period doubling bifurcations that leads to chaos, and state the experimentally observable signatures in the optical spectrum.

Optomechanical inertial sensors
Applied Optics, 2020 We present a performance analysis of compact monolithic optomechanical inertial sensors that describes their key fundamental limits and overall acceleration noise floor. Performance simulations for low-frequency gravity-sensitive inertial sensors show attainable acceleration noise floors on the order of 1 × 10 −

Single-Polariton Optomechanics [PDF]
Physical Review Letters, 2014 This paper investigates a novel hybrid cavity QED-optomechanics situation. We solve the Hamiltonian problem of a cavity coupled both to a two-level atom via a Jaynes-Cummings coupling and to a mechanical motion via radiation pressure coupling. The atom-cavity polariton number operator commutes with the total Hamiltonian leading to an exact analytical ...

Synchronization in an optomechanical cavity [PDF]
Physical Review E, 2015 We study self-excited oscillations (SEO) in an on-fiber optomechanical cavity. Synchronization is observed when the optical power that is injected into the cavity is periodically modulated. A theoretical analysis based on the Fokker-Planck equation evaluates the expected phase space distribution (PSD) of the self-oscillating mechanical resonator.

Optomechanically Induced Transparency [PDF]
CLEO:2011 - Laser Applications to Photonic Applications, 2010 Mechanical Transparency In atomic gases and other solid-state systems with appropriate energy levels, manipulation of the optical properties can be induced with a control pulse, allowing the system to transmit light of specific wavelengths that would otherwise have been absorbed.

Tailoring geometric phases of two-dimensional functional materials under light: a brief review
International Journal of Smart and Nano Materials, 2020 Information storage relies on the fast and reversible memory devices, which can read and write data easily with low energy input. In addition, in order to pursue high data storage density and miniaturizing device size, low-dimensional materials with ...

Nanoscale torsional optomechanics [PDF]
Applied Physics Letters, 2013 Optomechanical transduction is demonstrated for nanoscale torsional resonators evanescently coupled to optical microdisk whispering gallery mode resonators. The on-chip, integrated devices are measured using a fully fiber-based system, including a tapered and dimpled optical fiber probe.

Optomechanical Ramsey interferometry [PDF]
Physical Review A, 2014 We adopt the Ramsey's method of separated oscillatory fields to study coherences of the mechanical system in an optomechanical resonator. The high resolution Ramsey fringes are observed in the emission optical field, when two pulses separated in time are applied.

Two-membrane cavity optomechanics
New Journal of Physics, 2018 We study the optomechanical behaviour of a driven Fabry–Pérot cavity containing two vibrating dielectric membranes. We characterize the cavity mode frequency shift as a function of the two-membrane positions, and report a ∼2.47 gain in the optomechanical
