Abstract

In this paper, a gave a preview of targeted current research on integrated photonics based on the SU8 material was given. Such an approach takes advantage from a significant know-how regarding optical simulations by various analytical and numerical mathematical methods for the development of optical circuits on polymers. Original organic integrated photonics devoted to optical telecommunications and sensors applications on sundry waveguides structures, Mach-Zehnder interferometer (MZI), 2.5D and 3D Micro-resonators (MR), such as modulators, optical filters, devices for sensing pressure, gas and acid detections, heat flow measurements and future bio-detection schemes have been designed and realized last years. Present-day investigations deal with another main axis: The integration of 2.5D and 3D micro-resonator (MR) elements on photonic chips (optical add-drop filters circuits wavelength division de-multiplexing) which is under study, together with bio-sensors components based on the excitation of whispering gallery modes (WGMs) localized near the edge of the MR with sharp spectral resonance. Such  issues and their solving approach highlight the interest to develop in the future specific hybrid processes such as biomolecular film deposition, self-assembled growth and handling, plasma treatments coupled with microtechnologic thin layers processes and micro-fluidic devices.

Key words: Integrated photonics, waveguides structures, Mach-Zehnder interferometers, micro-resonators, organics materials.
