Abstract

The invention provides a high-speed modulator based on an annular reflector. The high-speed modulator comprises an input annular reflector, a modulation arm and an output annular reflector which are connected in sequence, wherein a resonant cavity is formed between the input annular reflector and the output annular reflector at the two ends of the modulation arm to enhance the light field energy density. The high-speed modulator has the advantages of being small in size, large in working bandwidth range, small in loss, simple in structure, easy to manufacture and suitable for large-scale manufacturing and commercial application.

Description

technical field [0001] The invention relates to a light modulation device, in particular to a high-speed modulator based on a ring reflector. Background technique [0002] The silicon optical modulator can realize high-speed data modulation and is one of the core devices of the high-speed silicon optical chip. In order to achieve high-speed transmission, the structure of traveling wave electrodes is usually used. The existing modulator structure has limitations in the dielectric constant and size of the manufacturing material, resulting in a large gap between the microwave group refractive index of the traveling wave electrode and the light wave group refractive index, so there is a large speed mismatch between the light wave and the microwave transmission. It will reduce the modulation bandwidth, and it is difficult to match the characteristic impedance to 50 ohms; at the same time, most modulator structures use silicon as the substrate, and there is still a large microwave...
