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 (17 o , 36 o and 54 o). 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.

“…Semiconductor metal oxides such as tin oxide (SnO), zinc oxide (ZnO) and indium oxide (InO) have been widely studied because they show useful optical and electronic properties [9]. SnO2 is a non-stoichiometric semiconductor with Eg (energy gap) > 3.6 eV at room temperature with a tetragonal structure.…”

This paper is about directional coupler fabrication results in a slab structure with a substrate in the form of acrylic glass, a film of nano SnO2, and cladding in the form of methyl methacrylate (MMA). The length of the interaction area (Lc) directional coupler of the fabrication result is 5 mm with a gap width (g) of 0.353 mm. SnO2 film is grown by deposition on an acrylic substrate. To facilitate the characterization process, the directional coupler is given an optical fiber as input. SnO2 film which has been deposited on an acrylic substrate is coated with methyl methacrylate (MMA). Coating of methyl methacrylate (MMA) in SnO2 film is done by the doctor blade method. Directional coupler fabrication results are used as optical power dividers. The fabricated directional coupler is narrated using a He-Ne laser with a wavelength of 632.8 nm. The characterization mechanism is carried out by taking a photo of the cross section of the directional coupler when given a laser beam input. The cross section photos are processed using ImageJ software to determine the directional coupler intensity distribution on each port. Based on the results of the characterization, the directional coupler with the 5 mm Lc output percentage is 26%, 24%, and 49%.

“…Several methods can be made for the manufacture of the waveguide with thin films, such as sol-gel method [10,11,12], Chemical Spray Pyrolysis [13][14][15], Chemical Bath Deposition [16], Chemical Vapor Deposition (CVD) [17].…”

The manufacture technology of thin film waveguides had done by placing a solution of tin dioxide (SnO 2 ) on the glass substrate. The structure of the straight waveguide consists of a slide glass substrate, waveguide using tin oxide film, and the cover waveguide is the MMA (Methyl Methacrylate) film. The method for making this waveguides, the waveguide was fabricated using the spin coating method and photolithography technique. The method for making this waveguides, the waveguide was fabricated using the spin coating method and photolithography technique. Analysis of the intensity of the input and output on a straight channels waveguide is done by an optical microscope with the light source of He-Ne laser. The results have obtained the multimode waveguides with the average thickness of straight channels is 16.67 μm.
