Wavelength Switching Hitless Optical Router Based on Microring Resonator

Abstract

The invention discloses a micro ring resonator-based wavelength switching-uninterrupted optical router, which comprises a first optical waveguide with a first-end input port and a first-end output port, a second optical waveguide with a second-end input port and a second-end output port, two micro rings, a first heater and a second heater, wherein the first-end input port of the first optical waveguide and the second-end output port of the second optical waveguide are coupled with the first micro ring respectively; the first micro ring and the second micro ring are coupled; the first heater modulates the first micro ring; and the second heater modulates the second micro ring. During a process with the resonant wavelength of the first micro ring switched to a wavelength 3 from a wavelength1, if optical signals with a wavelength 2 between the two wavelengths are inputted, the optical signals with the wavelength 2 are caused to be outputted from a downloading end due to resonance, and transmission of the optical signals with the wavelength 2 at a direct connection end is interrupted. Through modulation towards the second micro ring, on or off on the current resonant wavelength of thefirst micro ring is realized, and the purpose of an uninterrupted wavelength switching process is thus achieved.

Description

Technical field [0001] The invention relates to the technical field of switches for realizing wavelength switching without interruption in an on-chip optical interconnection network architecture, in particular to a microring resonator-based wavelength switching without interruption optical router. Background technique [0002] The existing interconnection networks are faced with increasing information flow and more and more processing ports, and its inherent limitations are becoming more and more difficult to conceal. Mainly because electrical interconnection methods have been unable to meet development needs in terms of bandwidth, energy consumption, and anti-interference. [0003] Due to the continuous development of research in recent years, interconnection methods based on optical signals have hoped to make up for or even replace electrical interconnections. On-chip optical interconnection has huge advantages in terms of bandwidth, energy consumption, and anti-interference tha...

Problems solved by technology

However, the optical wavelength switching of the current optical router needs to be modulated by the heater, and the resonant wavelength of the microring changes continuously, causing some optical signals that need to be passed through to resonate with the microring, and the transmission of optical signals is interrupted, thus affecting the entire optical interconnection network. transmission
