Problems solved by technology

Since this type of switch is based on the Kerr effect of light, the switching power is usually large, and the switching power can be reduced by increasing the length difference between the two interference arms, but this is not conducive to the miniaturization and integration of the device

Abstract

The invention provides a chalcogenide glass photonic crystal fiber 2*2 interference type all-optical switch which comprises a first coupler, a second couplers, a third coupler, a fourth coupler, a fifth coupler, a sixth coupler, a first chalcogenide glass matrix micro structure fiber, a second chalcogenide glass matrix micro structure fiber, a third chalcogenide glass matrix micro structure fiber, and a plurality of quartz single-mode fibers for connecting the above components. According to the switch, a chalcogenide glass material with a high nonlinearity effect and the photonic crystal fiber technology capable of generating a high nonlinearity effect are combined, a high speed light control 2*2 optical switch device is realized, at the same time, the switch is used as a basic unit to realize an n*n array, and uplink on-off and downlink on-off can be realized simultaneously or respectively.

Description

technical field [0001] The invention relates to the field of optically controlled optical switches, in particular to a chalcogenide glass photonic crystal fiber 2×2 interference all-optical switch and a control method. Background technique [0002] Optical switch is a device that can convert or logically operate optical signals in optical transmission lines or integrated optical circuits. It can realize functions such as dynamic optical path management, optical network fault protection, and dynamic wavelength allocation. Computing plays an important role in fields such as optical communication. Research on high-speed, high-sensitivity optical switches or optical switch matrices can solve the problem of wavelength contention in current complex networks, and is of great significance for improving wavelength reuse rate and flexible network configuration. Most of the traditional optical switches are electronically controlled optical switches. These switches usually have the dis...
