碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 97 === In this thesis, we propose a novel technique of fabricating an asymmetric Bragg coupled devices with polymer waveguides by using master molding of soft printing with the photolithography and holographic technique. First we made a ridge waveguides component through photolithography. We used the holography interference to implement a polymer Bragg waveguide component then with micro-contact printing of the soft printing, micro-molding in capillaries and replica molding to fabricate the molding of soft asymmetric Bragg coupled device with polymer waveguides component. Finally, we utilized formed soft waveguide molding along with polymer materials to implement an asymmetric Bragg coupled devices with waveguides component. It is easily to achieve the mass production. It has some advantages including process time shortening, low cost and lowest optical loss by using technique of soft molding of asymmetric Bragg coupled devices with polymer waveguide. In order to observation of the surface grating and record the results of this experiment accurately, we utilize the AFM (Atomic Force Microscopy) and SEM (Scanning Electron Microscopy ). Whereas the optical transmitting features are measured through the optical measuring system.
