Design and modeling of the ENR polymer microring resonators add/drop filter for wavelength division multiplexing

We report about design, modeling, fabrication and properties of the polymer optical microring resonator. First step was to design single mode optical polymer ridge waveguides by using BeamPROPTM software and then optical polymer microring resonator was designed by using FullWAVETM software. The design of the single mode waveguides was done for the operating wavelengths 650 nm and 1550 nm. The design of the microring resonators was done for operating wavelength 1550 nm and for elimination wavelength 1490 nm. The resonator was designed on the bases of optical polymer waveguides Epoxy Novolak Resin deposited onto silica-on-silicon substrate. We used Polymethylmethacrylate as cover layers, or eventually, no cover layer was applied. Deposition tests of the designed structures were done by using standard photolithography process and electron lithography process. Surface qualities of the fabricated samples were checked using optical microscope (Olympus DX60) and waveguiding properties were examined by Metricon 2010 prism-coupler system
