Abstract

The invention provides an optical module. The optical module comprises a circuit board, an arrayed waveguide grating AWG and an optical detector array which is arranged on the surface of the circuit board. Glue is coated on the surface of the optical detector array. The end of the AWG is an inclined surface. The glue is in contact with the AWG. The absolute value of the difference between the refractive index of the glue and the refractive index of the AWG is less than 10%. The light is reflected on the inclined surface of the AWG and incident to the surface of the optical detector array through the glue. According to the technical scheme, the glue is coated on the surface of the optical detector array, and the coupling efficiency can be improved and the coupling time can be shortened by using the simple optical path system, and the position accuracy requirement for each device in the optical path system can be reduced.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to an optical module. Background technique [0002] In the field of high-speed data communication, the integration of micro-optical assembly is getting higher and higher, and the optical system is becoming more and more complex. Especially under the premise that the size of the receiving end of the optical path is reduced and the accuracy is improved, the coupling efficiency of light and adapters becomes particularly important. . [0003] In the prior art, the way to improve the coupling efficiency of the light and the adapter is mainly to improve the coupling efficiency of the light and the adapter by reducing the light spot at the output end of the optical path by using lens combination. For example, a multi-lens coupled optical system may include a laser, a point-to-point lens, a collimator lens, a focusing lens, and a fiber adapter with an isolator, ...
