Abstract

The invention discloses a fundamental transverse mode microcolumn laser based on polymer. The laser comprises a substrate and at least a microcolumn optical unit. The optical unit is installed on the substrate. The optical unit comprises two distributed Bragg reflectors and a resonant cavity clamped between the two distributed Bragg reflectors. The distributed Bragg reflector has a periodic structure formed by alternated arrangement of thin polymer films in two different refractive indexes. The resonant cavity is made of an organic semiconductor or signal-layer polymer films doped with an active medium. A thin polymer film layer is processed by three different manufacturing methods. Through nanoimprint lithography, at least a microcolumn optical unit is imprinted, and a microlens structure is imprinted on the light outgoing end of the distributed Bragg reflector which is far away from a substrate. The laser is simple in manufacturing process, low in material and processing costs, and fast in processing speed, and is suitable for volume 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. ...
