Photoelectric chip and communication device

Abstract

A photoelectric chip and a communication device relate to the technical field of photoelectric chips, the photoelectric chip comprises a substrate, a laser and an optical device, the substrate is provided with an optical conduction part and an accommodating cavity which are adjacent to each other, a first waveguide is arranged in the optical conduction part, the first waveguide comprises at least two sub-waveguides which are arranged at intervals along a first direction, the projection parts of any two adjacent sub-waveguides in the at least two sub-waveguides along the first direction are overlapped, and the interval between the two adjacent sub-waveguides is within a preset range; the laser is located in the accommodating cavity, and the laser is in coupling connection with one of the first waveguides; the laser, the optical conduction part and the optical device are sequentially arranged, and the optical device is coupled with the other waveguide of the first waveguide. According to the invention, through the arrangement of the first waveguide and the coupling design of the plurality of sub-waveguides, the height of the laser position on different waveguides can be changed, the alignment of lasers with different light emitting heights and the waveguides is realized, the coupling degree is improved, and the coupling loss is reduced.
