Description

technical field [0001] The present application relates to the field of optical communication, in particular to an optical module. Background technique [0002] In optical fiber communication, wavelength-tunable optical modules have been widely studied. The wavelength tunable optical module can not only make full use of the bandwidth resources of the optical fiber in the DWDM system, but also greatly improve the communication capacity of the network system. It can be used as the backup light source of the traditional DWDM system, which is the key factor of the intelligent optical network. [0003] Although there are many ways to achieve tunable wavelengths, they usually require very complex optical design and manufacturing processes, ultra-high-precision control, etc., which are difficult to achieve, low yield rate of finished products, high manufacturing costs, large volume and other issues, which are not conducive to In commercial optical modules in batches.
