Abstract
The first fabrication and demonstration of narrowband channel-dropping filters, which have recently been proposed for use in high-bit-rate communication systems, is described. The devices use waveguide couplers combined with quarter-wave-shifted distributed-feedback (DFB) resonators and can, in principle, produce resonant transfer of 50% of incident power with sub-angstrom bandwidths. Resonant transfer of power at the expected wavelength and within the expected range of efficiency and bandwidth for this design is shown.Keywords
