摘要：A bandpass optical filter is provided that is formed within an optical fiber in theform of a Bragg grating. The grating includes multiple Fabry Perot cavities disposedalong the waveguide. Each of the cavities includes a pair of reflectors. Each reflectorcomprises alternating high- low index regions within the waveguide, each region having athickness of one quarter-wave at a bandpass wavelength, each alternate region being ofa different index of refraction than an adjacent region. A multiple odd quarter-wave orquarter-wave high or low index region is sandwiched between each pair of reflectors. Thenumber of high/low regions within a reflector is selected in accordance with the refractiveindex difference between two alternate adjacent regions.
