- Engraving of polymer materials using cutting laser is a popular process in some manufacturing industries. This research presents the manufacture of waveguides channels on polymethyl methacrylate (PMMA) substrate using CO2 cutting laser process. The CO2 laser engraving machine has cost effective and takes less time than other tools in waveguide channels fabrication. In this work, we integrated optical components such as waveguide for directional coupler application using tin oxide which is embedded and interconnected in PMMA substrate. In the fabrication channels waveguide with grafir on PMMA subtrate with 4.2 mW laser power and speed 10 mm/s and then repeated two times. The waveguide channels profile is made with curvature angle variation for branching (17o, 36o and 54o). Characterization of waveguide directional coupler is done by measuring the intensity of the output at each port cross-section of the waveguide directional coupler when given an input beam He-Ne laser (632.8 nm). The results directional coupler fabrication using CO2 laser cutting machine can achieve optimum with a very small loss of 3.3% when compared to the straight waveguide coupler channel. Thus, CO2 laser cutting processing as an optical waveguide fabrication can produce channels on PMMA material more effectively.
