Abstract

Summary form only given. Compact microring resonators are versatile devices which may become the basic building blocks of very large scale integrated photonic circuits. An important function which has been demonstrated with these resonators is spectral filtering. All filters made to date are of the all-poles type. All-poles filters alone are insufficient for more advanced filters like inverse-Chebyshev and elliptic, which require zeroes (notches). We present experimental realizations of two notch filters. In the course of fabricating these filters, we also succeeded in making low-loss (0.5 dB), wide-angle (50/spl deg/) Y-junctions.
