“…Owing to the overall sensitivity is proportional to the slope, it has been demonstrated that dispersive optomechanical coupling can enhance sensitivity by at least two orders of magnitude [160]. For engineering applications based on nonlinear effects in the optomechanical systems, in addition to introducing the second order optomechanical coupling for enhanced sensitivity in precision sensing for displacement [117][118][119]152], several nonlinear optomechanical models have been developed and analyzed for magnetic field [161,162], and electrical charge [163][164][165][166][167] sensing recently. Another proposal concept is the integration of a nonlinear mechanical resonator into cavity optomechanics.…”

A new class of hybrid systems that couple optical and mechanical nanoscale devices is under development. According to their interaction concepts, two groups of opto-mechanical systems are summarized as mechanically tunable and radiation pressure-driven optical resonators. On account of their high-quality factors and small mode volumes as well as good on-chip integrability with waveguides/circuits, photonic crystal (PhC) cavities have attracted great attention in sensing applications. Benefitting from the opto-mechanical interaction, a PhC cavity integrated opto-mechanical system provides an attractive platform for ultrasensitive sensors to detect displacement, mass, force, and acceleration. In this review, we introduce basic physical concepts of opto-mechanical PhC system and describe typical experimental systems for sensing applications. Opto-mechanical interaction-based PhC cavities offer unprecedented opportunities to develop lab-on-a-chip devices and witness a promising prospect to further manipulate light propagation in the nanophotonics.

“…Cavity optomechanical systems have potential applications in many fields, such as gravitational wave detectors [5], photon blockade [6,7], precision measurement [8,9], and force sensors [10]. Moreover, coherent manipulation of light [11,12], the optomechanically induced transparency (OMIT) [13,14], electromagnetically induced transparency (EIT) [15], and high-order sidebands [16][17][18][19][20][21][22] have been studied in detail. Especially, a broad overview of recent research progress on the topic of optomechanically induced transparency has been presented in ref.…”

“…Optical high-order harmonic generation was first successfully observed by Franken et al [24] and has developed potential applications in quantum information processing and optical communication. Nowadays, the second-order side-band [20][21][22] and the high-order sidebands [18,25] have attracted attention for their significant potential applications. The optical high-order sidebands generation is related to its input light, and these nonlinear optical effects can only be observed under the condition of the strong driving field or special driving pulse.…”

We theoretically investigate the optical second-order sideband generation (OSSG) in an optical parity-time (PT) symmetric system, which consists of a passive cavity trapping the atomic ensemble and an active cavity. Compared with the double-passive system, it is found that near the exceptional point (EP), the efficiency of the OSSG increases sharply not only for the blue probepump detuning resonant case but also for the red one. Using experimentally achievable parameters, we study the effect of the atomic ensemble on the efficiency of the OSSG in the PT-symmetric system. The numerical results show that the efficiency of the OSSG is 30% higher than that of the first-order sideband, which is realized easily by simultaneously modulating the atom-cavity coupling strength and detuning. Moreover, the efficiency of the OSSG can also be tuned effectively by the pump power, and the efficiency is robust when the pump power is strong enough. This study may have some guidance for modulating the nonlinear optical properties and controlling light propagation, which may stimulate further applications in optical communications. second-order sideband effects, parity-time symmetry, optomechanical system

Backaction Evading and Amplification of Weak Force Signal in an Optomechanical System

A scheme of backaction evading and amplification of weak force signal is presented in an optomechanical system. By introducing the frequency modulation of the cavity field, the system can achieve the quantum nondemolition measurement interaction so that the backaction evading can be reached. With the help of the mechanical squeezing, the weak force signal can be amplified, which equals to amplifying the mechanical response function, reducing additional noise as well as thermal noise of mechanical oscillator. The current scheme opens up an alternative method for simultaneously surpassing the standard quantum limit and enhancing the mechanical response, and also reducing the mechanical thermal noise.
