Abstract :
The pulse delay characteristics through all-pass filters with three coupled rings are measured and analyzed. The all-pass filters are fabricated in polymer material with large refractive index contrast between core and cladding. The measured d elay t ime i s 2 38ps and 330ps when two and three rings are in resonance, respectively. The experimental result agrees very well with the split-step time-domain simulation results.
