Method for manufacturing active optical waveguide

Fabrication of active optical waveguide by quantum dot formation

This technology relates to a method of manufacturing an active optical waveguide, which includes quantum dots that can fluoresce and amplify optical signals, and forms the quantum dots using a continuous oscillation laser.

With the existing technology, it is not easy to control the size or distribution while maintaining the characteristics of the quantum dots, and the process costs are high, making quantum dots practically impossible. There was a problem with not being able to utilize it. In order to solve this problem, this technology proposes a method of manufacturing a buried active optical waveguide containing quantum dots by inducing the precipitation of quantum dots in glass using a continuous oscillation laser.

By doing so, not only can a buried optical waveguide of the desired shape be manufactured, but it can also be very usefully applied in the fields of electronic device and optical irradiation manufacturing.
