EAGER:Coupled Optomechanical Resonators and Arrays

目的：本计画的目的是设计、制作及表征一种新型的光机械耦合共振器及阵列。芯片级光机械腔中的光子-声子相互作用是最近研究的主题，因为它们可以用于创建集成的混合光学/机械/量子信息处理系统。本计画将研究具有复杂复合共振功能的光机械耦合共振器与阵列。智力优点：智能的优点是使用耦合光学谐振相干控制和增强光机械相互作用的芯片级平台。在耦合光机械谐振器系统的强耦合状态下，分裂的光谐振将与光驱动场及其运动边带之一匹配，以增强光机械相互作用。在弱耦合机制中，由单独的谐振器中的相移引起的相反的光学力将用于同时冷却一个机械谐振器并加热另一个，以获得光学控制的机械能量传递。更广泛的影响：更广泛的影响是通过使用耦合光机械谐振器和阵列提供的多功能信息处理能力和极高的位移灵敏度来创建信号处理和传感平台。 该计划将资助一名全日制研究生，并通过建立创意探究团队和提供REU研究机会，让本科生参与与拟议研究相关的重点子项目。提出了一项广泛的外联工作，包括为本科生和高中生提供暑期实习计划，为高中教师举办科学讲习班。

Objective: The objective of this program is to design, fabricate, and characterize a new class of coupled optomechanical resonators and arrays. The photon-phonon interaction in chip-scale optomechanical cavities has been the subject of recent research as they can be used to create integrated hybrid optical/mechanical/quantum information processing systems. This project will investigate coupled optomechanical resonators and arrays with complex composite resonance functions. Intellectual merit: The intellectual merit is to use the coupled optical resonance to coherently control and enhance optomechanical interactions in a chip-scale platform. In the strong coupling regime of the coupled optomechanical resonator system, the split optical resonances will be matched to the optical driving field and one of its motion sidebands, to enhance optomechanical interactions. In the weak coupling regime, opposite optical forces induced by the phase shift in separate resonators will be used to simultaneously cool one mechanical resonator and heat the other to obtain optically-controlled mechanical energy transfers. Broader impacts: The broader impacts are to create signal processing and sensing platforms by using the versatile information processing capability and extremely high displacement sensitivity provided by coupled optomechanical resonators and arrays. This program will fund a full time graduate student and engage undergraduate students in focused sub-projects related to the proposed research through building Creative Inquiry teams and providing REU research opportunities. An extensive outreach effort is proposed, including a summer internship program for both undergraduate and high school students and a science workshop for high school teachers.
