摘要

考虑了一种基于两种光模的光机械系统，其中一种光模由相干波抽运，并通过声子模相互作用。在这种系统中，在双稳区可以实现硬激励模式。结果表明，用低强度种子波激发频率较低的光模可以显著降低硬激发模的阈值。这种减小是由于种子波改变了双稳区解的稳定性。这导致这样一个事实，即从非产生状态切换到产生状态发生在较低的泵浦波强度值。所得结果为全光晶体管和逻辑元件的创造铺平了道路。

Control of the threshold of the hard excitation mode of an optomechanical system by a low-intensity seed wave.

An optomechanical system based on two optical modes, one of which is pumped by a coherent wave, interacting with each other via a phonon mode is considered. In such a system, a hard excitation mode can be realized in the region of bistability. It is demonstrated that excitation of an optical mode with a lower frequency by a low-intensity seed wave can lead to a significant reduction of the threshold of the hard excitation mode. This decrease is due to the fact that the seed wave changes the stability of solutions in the bistability region. This leads to the fact that switching from a non-generating state to a generating one occurs at lower values of the intensity of the pump wave. The obtained result paves the way for the creation of all-optical transistors and logical elements.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
