Abstract [en]

Compact microracetrack resonator (MRR) devices are presented with small SU-8 polymer strip waveguides. The SU-8 strip waveguide has an SU-8 polymer core (n similar to 1.573), a SiO2 buffer (n similar to 1.445), and an air cladding. The fabricate straight waveguide has a low propagation loss of about 0.1. dB/mm. With such a high index-contrast optical waveguide, a compact MRR with a small bending radius (similar to 150 mu m) are designed and fabricated. The measured spectral responses of the through/drop ports show a Q-factor of 8000.
