Optomechanically induced transparency in a membrane-in-the-middle setup at room temperature

Abstract

We demonstrate the analog of electromagnetically induced transparency in a room temperature cavity\ud optomechanics setup formed by a thin semitransparent membrane within a Fabry-P´erot cavity. Due to destructive\ud interference, a weak probe field is completely reflected by the cavity when the pump beam is resonant with\ud the motional red sideband of the cavity. Under this condition we infer a significant slowing down of light of\ud hundreds of microseconds, which is easily tuned by shifting the membrane along the cavity axis.We also observe\ud the associated phenomenon of electromagnetically induced amplification which occurs due to constructive\ud interference when the pump is resonant with the blue sideband

Phase-dependent optical response properties in an optomechanical system by coherently driving the mechanical resonator

“…Usually, an amplifier based on optomechanical setup is realized by pumping the optomechnical cavity by a bluedetuned control field [13,14,26]. Our proposal shows that a red-detuned control field associating with an auxiliary driving applied to the mechanical resonator can also realize probe amplification.…”

“…Significant research interest in this frontier of optomechanics is motivated by its potential applications in ultrasensitive measurements, quantum information processing, and implementation of novel quantum phenomena at macroscopic scales [1][2][3][4]. Recently, a phenomenon resembling electromagnetically induced transparency (EIT) [5][6][7] in atomic physics, called optomechanically induced transparency (OMIT), is studied theoretically [8][9][10] and observed experimentally [11][12][13][14]. OMIT can be used for slowing and switching probe signals [15] and may be further used for onchip storage of light pulses via microfabricated optomechanical arrays [16].…”

“…On the other hand, optomechanically induced absorption (OMIA) phenomenon, which is an analog of electromagnetically induced absorption (EIA) investigated in atomic gas [21,22] and superconducting artificial atoms [23], can also be realized in optomechanical setup [13,24,25]. And OMIA is a phenomenon closely related to optomechanically induced amplification [13,14,[26][27][28].…”

“…Specifically, in standard OMIT [8][9][10][11][12][13][14] and OMIA [13,24], the coherent oscillation of the mechanical resonator results from a time varying radiation pressure force induced by the beat of the probe and the control laser. The oscillating mechanical resonator together with (red-/blue-detuned) control field can further induce sidebands on the cavity field.…”
