Flexible and Low-Cost Fabrication of Optical Waveguides Based on Sno2 for Passive Optical Devices

A process for fabricating fully integrated optical devices based on tin oxide material using a laser cutting method had been conducted. This study was able to create optical waveguide channels in a flexible and fast way using the method. The study also demonstrated that the laser cutting process was capable of fabricating a Y-double branch optical waveguide based on the core material SnO2 designed using the PMMA substrate. The fabrication structure was analyzed for the input and output of the optical waveguide design. In the future, this process will be enormous to improve the design and rapid manufacture of optical waveguide structures for passive optical device applications.
