Phase-dependent multiple optomechanically induced absorption in multimode optomechanical systems with mechanical driving

Enhancement of Upper Second-Order Sidebands Based on Optomechanically Induced Absorption in a Double-Cavity Optomechanical System

“…In detail, c 1 denotes the amplitude of the output field at the frequency of ω d1 , while c p represents the amplitude of the output field at the frequency ω d1 + ∆ p via the anti-Stokes process. Here we define the transmission rate of the probe pulse as This form of the transmission rate has been widely used to study the phenomena of OMIT and OMIA [1], [2], [3], [4], [5], [6], [7], [8], [9], [10]. To evaluate the conversion efficiency of the upper OSS, a dimensionless quantity used in Refs.…”

“…Since the sign of quantum interference (constructive or destructive) was proposed in cavity optomechanics [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], the investigations for linear and nonlinear optical responses in cavity optomechanical systems have rapidly become a growing topical research field [11], [12], [13], [14], [15], [16]. It is known that the physical origin of quantum interference is recognized as a special beat between intracavity scattered photons and mechanical motion induced by the time-varying radiation-pressure force [17].…”

“…It is known that the physical origin of quantum interference is recognized as a special beat between intracavity scattered photons and mechanical motion induced by the time-varying radiation-pressure force [17]. By modulating the relative phase of these intracavity scattered photons, this beat triggers two kinds of counterintuitive phenomena including optomechanically induced transparency (OMIT) [1], [2], [3], [4] and optomechanically induced absorption (OMIA) [5], [6], [7], [8], [9], [10]. As one of the centerpieces of modern optics, OMIT induced by destructive interference is characterised by a transparency window at the resonance position of a probe transmission spectrum.…”

“…As a counterpart of OMIT, the effect of OMIA induced by constructive interference can lead to a robust absorption peak within the transparency window, which has been introduced in the hybrid optomechanical systems with a multimode cavity [5], [6], [7], [8] or a parity-time-symmetric structure [9], [10]. Recent advances of these OMIA spectra have indicated the potential to realize the applications of signal amplification [7], [8] and quantum information networks [17]. Nevertheless, most of these advances of the OMIA spectra aim at manipulating and coding the incident signals in the linear regime without considering optical nonlinear effects [5], [6], [7], [8], [9], [10].…”

Thus, the correlation between the OMIA effect and the generation of nonlinear sideband spectra deserves more deep exploration.…”
