Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Schematic diagram of the role of mode switching in optical network systems, such as figure 1 shown. In the optical network system, mode 1 (Mode1) carries light with signal 1 forward, and mode 2 (Mode2) carries light with signal 2 forward. If the mode does not switch ( figure 1 The upper part, marked "Off"), the signal that the user gets at the receiving end is the light of mode 1 carrying signal 1 and the light of mode 2 carrying signal 2, which is exactly the same as the input signal; if the mode exchange occurs effect( figure 1 The lower part, marked with "On"), the light of mode 2 carrying signal 1 and the light of mode 1 carrying signal 2 can be received at the receiving end, and can be selectively switched or not according to user needs. Exchange, which undoubtedly greatly increases the availability and flexibility of network r...

Abstract

The invention discloses a reconfigurable arbitrary optical mode exchanger based on a micro-ring resonator. The reconfigurable arbitrary optical mode exchanger is composed of a demultiplexer, a micro-ring switch array and a multiplexer. The mode exchanger has a high reconfigurable characteristic, and the exchange between any two modes can be achieved. According to the mode exchanger, a relatively simple structure is adopted to introduce a wavelength switching function of traditional wavelength division multiplexing into a mode multiplexing system, and a certain promotion effect is provided forimproving the utilization rate and the flexibility of network resources in an optical communication system. In the aspect of device manufacturing, the exchanger can be realized on the basis of an SOImaterial, and can be completely compatible with the existing mature CMOS process, so that the exchanger is low in manufacturing cost, is easy to integrate with an electrical element, and is expected to have a good application prospect in the aspects of optical communication, optical interconnection and the like.

Description

technical field [0001] The invention belongs to the technical field of optical mode processing, and relates to a reconfigurable arbitrary optical mode switch based on a microring resonator. Background technique [0002] With the rapid development of the information age, people have put forward unprecedented high requirements for the capacity and speed of information processing and transmission. Traditional methods relying on reducing the size of on-chip transistors and increasing chip integration have encountered physical bottlenecks. At present, multi-core processors are becoming the mainstream way of microprocessor architecture. People have to find new ways to greatly increase the speed and capacity of information transmission, so as to reduce the information exchange time between cores and improve the overall work efficiency. and reliability. Silicon-based photonics is considered to be the most promising technical solution to this problem due to its low cost, high refra...
