    Abstract: The optical device includes a waveguide on a base. The device also includes a modulator on the base. The modulator includes an electro-absorption medium configured to receive a light signal from the waveguide. The modulator also includes field sources for generating an electrical field in the electro-absorption medium. The electro-absorption medium is a medium in which the Franz-Keldysh effect occurs in response to the formation of the electrical field in the electro-absorption medium. The field sources are configured so the electrical field is substantially parallel to the base.

    Abstract: An optical device includes an echelle grating and input waveguide arrange d such that the echelle grating receives an input signal that exits from a p ort of the input waveguide. The echelle grating is configured to reflect the input signal such that when the input signal has a plurality of channels, t he input signal separates into output signals that each includes a different one of the channels. The device also includes a plurality of output wavegui des that each includes a port positioned to receive one of the output signal s. The output waveguides include central waveguides. The central waveguides are the three centermost output waveguides when the total number of output w aveguides is odd and the two centermost output waveguides when the total num ber of output waveguides is even. The central waveguides are positioned such that the grating axis passes through the port associated with one of the ce ntral waveguides or passes between the ports associated with the central wav eguides.

    Abstract: The ring resonator includes waveguides configured to guide light signals. The waveguides include an input waveguide and one or more loop waveguides. One of the loop waveguides is a primary loop waveguide that is optically coupled with the input waveguide at a wavelength of light. A tuner is configured to tune the wavelength at which the light is optically coupled from the input waveguide into the primary loop waveguide. One or more light detectors are each configured to provide an output indicating an intensity of light guided in one of the one or more loop waveguides. Electronics are configured to tune the tuner in response to the output from the light detector.

    Abstract: An optical system includes an optical device having waveguides defined in a first light transmitting medium. The optical device includes stops extending upward from a laser platform. The system also includes a laser bar having a plurality of lasers. The laser bar is positioned on the platform such that each laser is aligned with one of the waveguides. The laser bar includes alignment trenches that each includes a secondary stop extending upward from a bottom of the alignment trench. The secondary stop includes layers of material having different composition. The stops each extend into an alignment trenches such that each stop contacts one of the secondary stops.
