Embodiment 1

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 The shown butterfly laser comprises a casing 1 and a laser chip 31, a beam splitter 32, an optical isolator 37, a prism 33, a photodetector 34, a fiber collimator 35, an optical fiber 36, Leads 4 connected to the laser chip, the laser chip, beam splitter, optical isolator 37 , prism, photodetector, fiber collimator, optical fiber, and leads 4 are integrated into a single package structure 2 . The process of integrating and packaging laser chips, beam splitters, optical isolators, prisms, photodetectors, fiber collimators, and optical fibers into a package structure can be realized in many existing factories. The beam splitter divides the laser light from the laser chip into two paths, and one leads to the photodetector. The photodetector detects the light and uses the current to calculate the voltage to identify the level of the laser emitted by the laser chip. The control of the amount of emitted laser light, the ...

Embodiment 2

[0027] Based on the structure of the above embodiment, this embodiment refines the above structure, that is, the package structure 2 is fixed in the package 3, and the package 3 is provided with a heating component 72, a cooling component 73 and a temperature detection device for monitoring the temperature 71. The heating component can be realized by using a heat conduction sheet made of superconducting material, so as to control the temperature.

[0028] There are many ways to install the packaging structure. For example, the packaging structure 2 is directly fixed on the package in a cylindrical shape, such as figure 1 shown. On this basis, threads can also be provided outside the package structure 2, and screw holes matching the threads of the package structure 2 can be provided on the package 3 to improve heat conduction efficiency. It is also possible to have two sets of springs in the packaging structure. In order to avoid the influence of the springs on the leads, an ...
