摘要： A multi-path interference filter. The multi-path interference filter includes a first port waveguide, a second port waveguide, and an optical structure connecting the first port waveguide and the second port waveguide. The optical structure has a first optical path from the first port waveguide to the second port waveguide, and a second optical path, different from the first optical path, from the first port waveguide to the second port waveguide. The first optical path has a portion, having a first length, within hydrogenated amorphous silicon. The second optical path has a portion, having a second length, within crystalline silicon, and the second optical path has either no portion within hydrogenated amorphous silicon, or a portion, having a third length, within hydrogenated amorphous silicon, the third length being less than the first length.

摘要： A single mode waveguide with a straight portion and a curved portion, the curved portion having the shape of an adiabatic bend. The single mode waveguide has a curved portion that is shaped according to an adiabatic bend, with a curvature that varies continuously, and that vanishes at a point at which the curved portion is contiguous with a straight portion of the waveguide. The absence of curvature discontinuities avoids the coupling, within the waveguide, of optical power from a fundamental mode into a higher order mode and the curvature of the curved portion results in attenuation of optical power, in higher order modes, that may be coupled into the waveguide at either end.

摘要： An interposer chip for coupling light between an array of fibers and an array of optical waveguides on a second photonic chip. The interposer chip has an array of V-grooves for aligning the ends of the fibers to corresponding ends of an array of optical waveguides on the interposer chip. Each optical waveguide has a taper with a first end and a second end, the first end being configured to support an optical mode that couples efficiently to the mode of an optical fiber. The taper reduces the vertical mode size, so that the mode supported by the second end of the taper may be efficiently coupled to a 3-micron thick optical waveguide on the second photonic chip. The interposer chip further has a hard stop having a flat surface parallel to the optical waveguides on the interposer chip, at the interface to the second chip. When the interposer chip is flipped and assembled with the second chip, the hard stop abuts against a mounting surface on the second chip, so that optical waveguides on the interposer chip are aligned, in the vertical direction, with optical waveguides on the second chip.
