Abstract

In this letter we describe the first fabrication and demonstration of narrow-band channel-dropping filters which have recently been proposed for use in high-bit-rate communication systems. The devices use waveguide couplers combined with quarter-wave shifted DFB resonators and can, in principle, produce resonant transfer of 50% of incident power with sub-angstrom bandwidths. Our results show resonant transfer of power at the expected wavelength and within the expected range of efficiency and bandwidth for our designs. © 1992 IEEE
