The goal of this CNIC proposal is to catalyze an international collaboration between the University of Southern California (USA) and KIST (Korea). The focus of the research effort is to develop an integrated optical switch and a pulsed laser based on a graphene coated silica micro-toroid resonant cavity. As a result of the extremely high non-linear coefficient of graphene and the long photon lifetime within the optical cavity, femtosecond laser pulses will be generated. This behavior can be used as an ultra-fast optical switch, among other applications. During the course of the program, graphene layers will be conformally deposited on silica toroidal microcavities as well as optical fibers. Subsequently, light will be coupled into the graphene-silica fiber and cavity, and the high frequency pulse behavior will be studied and characterized.Ultrafast optical switches have numerous applications, most notably increasing the data transfer rate of optical networks. As such, the development of an optical switch with improved performance (speed, lifetime or power consumption) will greatly impact society. The proposal will enable a graduate student to spend time abroad in the collaborator's research group in Korea, immersed in their lab. The outreach effort supported by this CNIC proposal includes recruiting undergraduate students to participate in year-long research projects, and incorporating research experience in an undergraduate course. This CNIC award is funded by the International Science and Engineering section (OIIA/ISE) with co-funding from the Electrical, Communications and Cyber Systems division of Engineering (ENG/ECCS).

该建议的目的是催化南加州大学（美国）和凯斯特（韩国）之间的国际合作。研究工作的重点是基于石墨烯涂层的二氧化硅微螺纹谐振腔开发集成的光学开关和脉冲激光器。由于石墨烯的极高非线性系数和光腔内的长光子寿命，将产生飞秒激光脉冲。此行为可以用作超快速的光学开关。在程序的过程中，石墨烯层将共同沉积在硅环形微腔和光纤上。随后，光将耦合到石墨烯 - 硅纤维和空腔中，并将研究高频脉冲行为。因此，开发具有提高性能（速度，生命周期或功耗）的光学开关将极大地影响社会。该提案将使一名研究生能够在韩国合作者的研究小组中度过国外的时间，并沉浸在他们的实验室中。这项CNIC建议支持的外展工作包括招募本科生参加为期一年的研究项目，并将研究经验纳入本科课程。该CNIC奖由国际科学与工程部（OIIA/ISE）资助，并由电气，通信和网络系统工程部（ENG/ECCS）共同资助。
