Problems solved by technology

[0003] The existing white light laser usually needs to be composed of three independent lasers of red, green and blue, and needs to be adjusted and integrated into the same output of the external optical path, and the overall volume is relatively large; at the same time, in order to form a white color spectrum, the three lasers need to be adjusted separately. The output power is also more complicated in the adjustment scheme

Embodiment Construction

[0024] The present invention will be further described below through specific embodiments.

[0025] Figure 1 to Figure 4 , a miniature white light laser, including a microfluidic chip 30 and three laser diodes 10 and three micron optical waveguides 20 packaged inside. The input ends 21 of the three micron optical waveguides 20 are located on the light-emitting surfaces 11 of the active regions of the three laser diodes 10 in one-to-one correspondence. One of the micron optical waveguides 20 serves as a backbone and is coupled with the output ends 22 of other micron optical waveguides 20 to synthesize white light, and its output end 22 is used as a white light output end.

[0026] Specifically, three laser diodes 10 respectively output red light, green light and blue light, and three micron optical waveguides 20 are coupled to form a 1×3 branch structure, including three input terminals 21 , one output terminal 22 and two coupling regions 23 . The micron optical waveguide 20...

Abstract

The invention discloses a mini white-light laser and a manufacture method thereof. The mini white-light laser comprises a microfluidic chip, a plurality of laser diodes and a plurality of micron lightwaveguides. The laser diodes and the micron light waveguides are packaged in the microfluidic chip. Input ends of the micron light waveguides are located on light outlet surfaces of active regions ofthe laser diodes in one-to-one correspondence. One of the micron light waveguides is coupled with output ends of the other micron light waveguides to form white-light output ends. The mini white-light laser has the advantages of simple structure, high integration degree and the like, and plays an important role in the fields such as white-light source microminiaturization, machine vision and biological medicine.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a miniature white light laser and a manufacturing method thereof. Background technique [0002] At present, due to the advantages of high energy, good monochromaticity, and good coherence, lasers have played an important role in many aspects such as communication, precision instrument manufacturing, high-precision measurement, display lighting, and medical diagnosis since their invention. White light laser sources are better than ordinary white light sources in terms of brightness and coherence. Therefore, white light lasers have great application prospects in color display, medical diagnosis, and machine vision. [0003] The existing white light laser usually needs to be composed of three independent lasers of red, green and blue, and needs to be adjusted and integrated into the same output of the external optical path, and the overall volume is relatively large; at the same time, in order...
