Integrated polymers (PVCi/PMATRIFE) microring resonators for low power tunable filters

Abstract : In this paper we present optical and thermo-optical characterization results of integrated filters based on micro-ring resonators fabricated with a couple of polymers ''PVCI/PMATRIFE''. Their high index contrast (Dn 0.15 at the wavelength of 1550 nm) allows to make small size waveguides with cross sections of 1.5 1.5 mm2. The study of the impact of different gaps on the extinction ratio and FWHM (full width at half maximum) of filters leads to a better design. First experiments of thermal tunability of the microring filter using a thermo-electric cooler (TEC) are also reported giving a 5 nm shift of the dropped wavelength for a temperature change of 40 K. The fabrication of gold electrodes on microrings is reported and the electrical power required for the tuning of the drop wavelength of 0.0055 nm/1 mW show that with an optimized electrode design the consumption will be low.
