Abstract

The invention discloses a polymer-based fundamental transverse mode micro-cylindrical laser, which includes a substrate and at least one micro-cylindrical optical unit, the optical unit is installed on the above-mentioned substrate, and the optical unit includes two distributed Bragg reflectors and two Resonant cavity sandwiched between distributed Bragg reflectors. The distributed Bragg reflector has a periodic structure formed by alternate arrangement of two polymer films with different refractive indices; the resonant cavity is made of an organic semiconductor or a single-layer polymer film doped with an active medium. Three different manufacturing methods are used to process the polymer film layer, and at least one micro-cylindrical optical unit is pressed by nano-imprinting technology, and a micro-lens structure is pressed at the light exit end of the distributed Bragg reflector away from the substrate . The manufacturing process is simple, the cost of materials and processing is low, the processing speed is fast, and it is suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of lasers, in particular to a polymer-based fundamental transverse mode microcolumn laser. Background technique [0002] In the prior art, miniaturization and integration are an inevitable trend in the development of lasers. With the reduction of the characteristic size of lasers, the manufacturing process of lasers becomes complicated, which reduces the manufacturing efficiency and increases the cost. [0003] The distributed Bragg reflector (DBR) of the laser has a periodic structure in which two semiconductor materials with different refractive indices are arranged alternately in an ABAB manner. Semiconductor materials are commonly used as thin film materials, and the difference in refractive index of semiconductor materials is small. Therefore, semiconductor materials It is necessary to use more layers to obtain high reflectivity, which is not conducive to simplifying the process and reducing the cost. ...
