摘要： Multiple Bragg gratings are fabricated in a single planar lightwave circuit platform. The gratings have nominally identical grating spacing but different center wavelengths, which are produced using controlled photolithographic processes and/or controlled doping to control the effective refractive index of the gratings. The gratings may be spaced closer together than the height of the UV light pattern used to write the gratings.

摘要： Optical circuits having a flat wavelength response are disclosed. A disclosed apparatus includes a first optical coupler, first and second optical waveguides optically coupled to the first optical coupler and a second optical coupler optically coupled to the first and second optical waveguides. The first optical coupler couples input light into a first portion and a second portion. The first and second optical waveguides receive the first and second portions of input light from the first optical coupler, respectively the second optical coupler couples the first portion of input light from the first optical waveguide and the second portion of input light from the second optical waveguide. The second optical waveguide may effect a fixed phase difference of one-half wavelength relative to the input light. The first and second optical couplers may have first and second wavelength dependences, respectively, where the second wavelength dependence is opposite the first wavelength dependence.
