Paper Abstract

This paper presents a design for rectangular ring resonators based on low-index polymers operating at an 850 nm wavelength. Multimode interference couplers are used to enable signal splitting and combining and air trench assisted 90° mirrors are used as beam turning elements. 3D full-vector, 2D FDTD and parameter models are combined to simulate the ring resonator design. This design, suitable for spectral shaping, achieves a FSR of 0.29 nm, a FWHM of 0.066 nm and an on-off ratio of approximately 20 dB.
