Title:
MICRO-RING MODULATOR AND OPTICAL SIGNAL TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/122939
Kind Code:
A1
Abstract:
Provided in the present application are a micro-ring modulator and an optical signal transmission method, which can reduce the number of devices in the micro-ring modulator, thereby reducing the size of the micro-ring modulator, and reducing the power consumption and the manufacturing costs of the micro-ring modulator. The micro-ring modulator in the present application comprises a first annular waveguide, a first PN junction, a first controller and a second controller. When the micro-ring modulator is in operation, the first controller can send a first electrical signal to the first annular waveguide, and the second controller can control the state of the first PN junction that is deployed on the first annular waveguide. Thus, when the first PN junction is in a forward bias state, the first annular waveguide can transmit, under the effects of the first electrical signal and the first PN junction, a first optical signal having a first wavelength; and when the first PN junction is in a reverse bias state, the first annular waveguide can transmit, under the effects of the first electrical signal and the first PN junction, a second optical signal having a second wavelength.
