Polymer optical micro-ring resonators

Micro-ring resonators are compact, versatile optical devices with applications in telecommunications and sensing. We are investigating polymers as our material platform because polymers can have high optical nonlinearities, low absorption loss, allow easy device fabrication, and offer a great variety of material properties. We have designed and fabricated filters using arrays consisting of over 100 micro-rings with very low throughput loss (<3 dB) yet broad bandwidth. High quality micro-rings have also been fabricated using MAP.
