Problems solved by technology

[0003] Although WGM micro-lasers have made great research progress, the coupling output of the laser and the integration with optical fibers have always been technical problems, which seriously hinder the development of WGM micro-lasers in the field of optical fiber sensing and information.
At present, existing solutions include semiconductor nanowire and microfiber composite structure microlaser (such as CN200810164186.9) and multi-wavelength semiconductor nanowire and microfiber composite structure microlaser (CN200910154254.8), which can effectively convert the generated The laser is coupled out through the optical fiber, however, the complexity of the device fabrication and the instability of the work limit its application
