Description

technical field

[0001] The invention relates to the technical field of lasers, in particular to a butterfly laser. Background technique

[0002] At present, the optical transmitter component is the core device of modern optical fiber communication. High-speed optical transmitters of 10Gb / s and above are usually packaged in a butterfly package to improve the high-frequency performance of the device. The existing butterfly laser includes a casing, a thermistor placed in the casing, a laser chip and other components. The space in the casing is narrow, and each component needs to be packaged in the casing during processing, and the packaging accuracy is related to the coupling efficiency of the butterfly laser. In order to obtain higher coupling efficiency, the processing requirements are high, the processing procedures are complex and the efficiency is low. Contents of the invention

[0003] The present invention provides a butterfly laser in order to solve the above techni...
