ABSTRACT:
A four-port optical filter is provided including two tapered optical fibers, each having a loop in the area of their tapered portions, which are located relative to one another to form a ring resonator. The optical filter has a low Q with a broadband filter response which is useful as a channel interleaver or de-interleaver for dense wavelength division multiplexing and other applications.
