Abstract

The invention discloses a crystal and a manufacturing method thereof; the crystal has an incident plane and an exit plane, and used for splitting a laser emitted on the crystal from the incident plane, thus forming a first light and a second light; the first light exits from the exit plane, and the second light exits from the incident plane. The crystal can split the laser without adding a light splitting film; the light splitting method is good in stability, and can reduce the optical device failure risks.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and more specifically relates to a crystal and a manufacturing method thereof. Background technique [0002] In recent years, the global cloud service market has continued to rise, benefiting from the demand for network communication and data communication. Driven by the dual power of the telecom market and the data center market, the optical fiber communication industry has developed rapidly, and the demand for high-speed optical modules is also gradually increasing. . [0003] In practical applications, the light of the optical module is output by the laser, and the stability of the optical power of the laser is affected by many factors. For example, the heating of the laser itself, the ambient temperature and humidity, the working time of the laser, the change of the threshold current, and the heat dissipation of the optical module will all affect the stable output of the optica...
