ABSTRACT:
A two-ring optical buffer comprising a first ring operatively connected to a waveguide and a second ring, the second ring being operatively connected to only the first ring, the second ring and the first ring having a circumferential ratio substantially equal to 2m, where m is an integer. A ratio of resonance splitting over resonance broadening may be approximately 0.6.
