Abstract

The invention discloses a modulator and a modulation method, and the modulator comprises a 1 * 2 beam splitter, a first phase shifter, a second phase shifter, a 2 * 2 beam splitter, a first gradient waveguide, a second gradient waveguide, an electro-optical modulator, and a beam combiner. The input end of the 1 * 2 beam splitter is connected with a light source, the first output end and the second output end of the 1 * 2 beam splitter are respectively connected with the first input end of the 2 * 2 beam splitter and the input end of the first phase shifter, and the output end of the first phase shifter is connected with the second input end of the 2 * 2 beam splitter; the first output end of the 2 * 2 beam splitter is connected with the input end of the first tapered waveguide, the output end of the first tapered waveguide is connected with the input end of the electro-optical modulator, the output end of the electro-optical modulator is connected with the input end of the second tapered waveguide, and the output end of the second tapered waveguide is connected with the first input end of the beam combiner; the second output end of the 2 * 2 beam splitter is connected with the input end of the second phase shifter, the output end of the second phase shifter is connected with the second input end of the beam combiner, and the output end of the beam combiner outputs first interference light.

Description

technical field [0001] The embodiment of the present application relates to the field of optical communication devices, and relates to but not limited to a modulator and a modulation method. Background technique [0002] Since the silicon-based modulator is compatible with a mature complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) process, it can be processed and manufactured on a large scale, reducing the manufacturing cost of the device. [0003] The Mach-Zehnder silicon-based modulator is a common silicon-based modulator. The traditional Mach-Zehnder silicon-based modulator has problems such as large structure size and high power consumption. In addition, for the traditional Mach-Zehnder type silicon-based modulator, due to the low extinction ratio, it leads to problems such as high bit error rate. Contents of the invention [0004] In view of this, the embodiments of the present application provide a modulator and a modulation met...
