Chaotic Dynamics and Optical Power Saturation in Parity-Time (PT) Symmetric Double Ring Resonator
Jyoti Prasad Deka, Amarendra K. Sarma
We report emergence of saturation and chaotic spiking of optical power in a double ring resonator with balanced loss and gain, obeying the so-called parity-time symmetry. We have m…
Single Photon Generation in a Cavity Optomechanical System induced by a Nonlinear Photonic Crystal
Bijita Sarma, Amarendra K. Sarma
We propose a novel scheme for realizing single-photon blockade in a weakly driven hybrid cavity optomechanical system consisting of a nonlinear photonic crystal. Sub-Poissonian sta…
Efficient shortcut techniques in evanescently coupled waveguides
Koushik Paul, Amarendra K. Sarma
Shortcut to Adiabatic Passage (SHAPE) technique, in the context of coherent control of atomic systems has gained considerable attention in last few years. It is primarily because o…
Enhanced terahertz transmission through a periodic array of tapered rectangular apertures
Koijam Monika Devi, Amarendra K. Sarma, Gagan Kumar
We numerically analyse extraordinary terahertz transmission properties of an array of rectangular shaped apertures perforated periodically on a thin metal film. The apertures are t…
Atom assisted cavity cooling of a micromechanical oscillator in the unresolved sideband regime
Bijita Sarma, Amarendra K Sarma
The ground state cooling of a mechanical oscillator in an optomechanical cavity containing an ensemble of identical two-level ground-state atoms is studied in the highly unresolved…
Optical bistability and cooling of a mechanical oscillator induced by radiation pressure in a hybrid optomechanical system
Bijita Sarma, Amarendra K. Sarma
We investigate theoretically the effect of optical feedback from a cavity containing an ultracold two level atomic ensemble, on the bistable behavior shown by mean intracavity opti…
