Problems solved by technology

In the prior art, in order to solve the temperature-sensitive characteristics of silicon-based AWG chips, temperature controllers and temperature control circuits are usually used to stabilize the central output wavelength; however, this also increases the cost and size of AWG chips, and limits the application range of AWG
The stability of the fixed base of the existing AWG chip is poor, and the heat dissipation performance is not good, resulting in a reduction in the life of the AWG chip

Abstract

The invention provides a base for fixing an arrayed waveguide grating (AWG) chip. The base comprises a base body and a compensation adjustment screw. The base body comprises a first sub-base with a convex portion and a second sub-base with a concave portion. The convex portion matches the concave portion and is disposed in the concave portion. The first side portion of the second sub-base is provided with a chip channel and a protrusion protruding from the first side portion. The convex portion includes a first support plate and a second support plate arranged in a V shape. The first support plate is provided with a first groove at a side adjacent to the concave portion. The second support plate is provided with a second groove at a side adjacent to the concave portion. The compensation adjustment screw is arranged between one end portion of the second support plate and the protrusion. By cutting the base and configuring the compensation adjusting screw, when the AWG chip on the base changes by being affected by temperature, the thermal expansion and contraction of the compensation adjusting screw moves a planar waveguide so as to compensate for the influence of the temperature change on the center wavelength of the AWG.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a base for fixing arrayed waveguide grating chips. Background technique [0002] With the rapid development of communication technology and its business, the research of large-capacity optical fiber communication system has great application value. The maximum transmission capacity of optical fiber obtained so far is only equivalent to 0.24 of its potential capacity. Coarse wavelength division multiplexing (CWDM) technology can tap the transmission potential of optical fiber well. Its research and application are going on at the same time. Optical devices based on arrayed waveguide gratings (AWG) have important application prospects in WDM technology, and their research and development work has developed rapidly in recent years. [0003] The concept of AWG was first proposed by Smit of Delft University in the Netherlands in 1988. Its important application value has attr...
