Wavelength switching no-interruption optical router based on microring resonator and Mach-Zehnder modulator

Abstract

The invention discloses a wavelength switching no-interruption optical router based on a microring resonator and a Mach-Zehnder modulator. The optical router comprises a first optical waveguide with afirst 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; a microring resonant cavity; a third optical waveguide with a third end input port and a third end output port; a first heater; and a second heater. The first end input port of the first optical waveguide and the second end output port of the second optical waveguide are coupled to the microring resonant cavity. A part of the waveguide of the microring resonant cavity is taken as an arm which forms the Mach-Zehnder modulator with the third optical waveguide.The third end input port and the third-end output port are coupled to the microring resonant cavity. The first heater modulates the micro-ring resonance a cavity, and the second heater modulates the third optical waveguide. The optical router achieves the switching of the resonant wavelength of the current resonant cavity through the modulation of the Mach-Zehnder modulator, thereby achieving a purpose that there is no interruption in the wavelength switching process.

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 wavelength switching non-interruption optical router based on a microring resonator and a Mach-Zehnder modulator. Background technique [0002] Facing the ever-increasing information flow and more and more processing ports of the existing interconnection network, its inherent limitations are becoming more and more difficult to hide. The main reason is that the electrical interconnection method has been difficult to meet the development needs in terms of bandwidth, energy consumption, and anti-interference. [0003] Due to the continuous development of research in recent years, the interconnection method based on optical signal has the hope of making up for or even replacing the electrical interconnection. On-chip optical interconnection has huge advantages in ban...

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
