摘要： The system includes a light-transmitting medium positioned on a base. The light-transmitting medium included a ridge and a slab region. The ridge extends upward from the slab region and defines a portion of a waveguide on the base. The waveguide is configured to guide a light signal through the device. The device also includes an avalanche effect light sensor positioned on the base and configured to detect the presence of the light signal. The light sensor includes a light-absorbing medium positioned on the ridge of the light-transmitting medium such that the light signal is coupled from the light-transmitting medium into the light- absorbing medium. The light-transmitting includes a charge layer located at an interface of the light-transmitting medium and the light-absorbing medium. A multiplication region is formed in the slab regions of the light-transmitting medium such that the multiplication region receives charge carriers from the charge layer during the operation of the light sensor.

摘要： An optical device includes an echelle grating and input waveguide arranged such that the echelle grating receives an input signal that exits from a port 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, the input signal separates into output signals that each includes a different one of the channels. The device also includes a plurality of output waveguides that each includes a port positioned to receive one of the output signals. The output waveguides include central waveguides. The central waveguides are the three centermost output waveguides when the total number of output waveguides is odd and the two centermost output waveguides when the total number of output waveguides is even. The central waveguides are positioned such that the grating axis passes through the port associated with one of the central waveguides or passes between the ports associated with the central waveguides.
