Electro-optical intensity modulation apparatus, chip and system

Abstract

An electro-optical intensity modulation apparatus has a non-linear optical substrate and electrodes. The non-linear optical substrate is provided with a first branch waveguide, a second branch waveguide, a first channel waveguide and a second channel waveguide thereon. The first channel waveguide and the second channel waveguide are disposed between the first branch waveguide and the second branch waveguide, and the first channel waveguide and the second channel waveguide are branched from the first branch waveguide and converged at the second branch waveguide. The electrodes are disposed on an area between the first branch waveguide and the second branch waveguide to make the first channel waveguide, the second channel waveguide and the electrodes form a radio frequency conversion push-pull electro-optic phase modulation unit, a push-pull electro-optic bias control unit, two sets of independent polarization rotation control units and a dual-channel relative light intensity ratio adjustment unit, which are sequentially connected.
