Abstract

The invention discloses an electrically controlled micronano optical fiber optical switch based on a graphene thin film. The electrically controlled micronano optical fiber optical switch comprises a tapering light output micronano optical fiber, a tapering light input micronano optical fiber and a circuit control module based on the graphene thin film, wherein in the circuit control module based on the graphene thin film, a silicon base coated with the graphene thin film is used as a center; a metal electrode is arranged on the rim of the silicon base; the tapering light output micronano optical fiber and the tapering light input micronano optical fiber are oppositely arranged on the graphene silicon base; the ends of the two micronano optical fibers are adsorbed together by a van der Waals force, and serve as a coupling end of a light path; and ultraviolet photoresist with low refractive index is coated on the micronano optical fibers. On the basis of the property of graphene, the novel optical fiber optical switch has the characteristics of small size, short response time, low driving voltage and improved reliability by combining the evanescent wave characteristics of the micronano optical fibers.

Description

technical field [0001] The invention relates to the field of optics, in particular to an electronically controlled micro-nano optical fiber switch based on a graphene film. Background technique [0002] With the development of the information age, people have put forward new requirements for information capacity and transmission speed, and the traditional electrical signal processing speed has encountered a bottleneck. How to reliably process high-speed data has become a challenge for researchers. big challenge. An all-optical network that can provide huge bandwidth and process data at high speed may be a lifesaver. There are two important components in an all-optical network, namely optical cross-connect (OXC) and optical add-drop multiplexing (OADM), and the optical switch, as the core component of an optical cross-connect (OXC), has important research significance. [0003] The earliest researched solid-state optical switches, such as electro-optic switches, thermo-opti...
