摘要：A resonant optical filter includes first and second transmission waveguides anda resonator (including one or more evanescently coupled resonator segments). Theresonator supports at least one circumferential resonant mode and is evanescentlycoupled to the waveguides. An optical signal entering the filter through a waveguide andsubstantially resonant with the resonator is transferred to the other waveguide, while anoptical signal entering the filter and substantially non-resonant with the resonatorremains in the same waveguide. Multiple resonator segments may be formed on acommon resonator fiber and positioned for enabling coupling between them, resulting ina tailored frequency filter function. The resonators may include alignment structure(s)(flanges, grooves, etc) for enabling passive positioning and/or supporting first andsecond transmission waveguides, such as optical fiber tapers. Structures may also beprovided for suppressing undesired optical modes and/or resonances associated with theresonators and/or alignment structures on the resonator fiber.
