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 900 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.
