Abstract: An optical component is disclosed. The optical component includes an input waveguide having an expansion region expanding from an input port to a multimode port. The expansion region is configured to receive a light signal through the input port. An array waveguide grating is configured to receive a light signal from the expansion region of the input waveguide. An output waveguide has an output port configured to receive the light signal from the array waveguide grating. The output port has dimensions that are different from dimensions of the input port. In some instances, a function expressing the expansion from the input port to the multimode port includes an exponential function and/or a sinh function.

Abstract: An optical filter system is disclosed. The optical filter system includes a first filter configured to output light signals having wavelengths falling within a plurality of periodically spaced wavelength bands. A second filter in optical communication with the first filter and being configured to output light signals having wavelengths falling within a plurality of periodically spaced bands. The period of the bands associated with the first filter is different than the period of the bands associated with the second filter.

Abstract: The optical component includes an array waveguide grating having a plurality of array waveguides. The optical component also includes a light distribution component configured to receive a light signal through an inlet port and distribute the light signal to a plurality of the array waveguides. The optical component further includes an output light distribution component configured to receive the light signal distributed to the array waveguides. The light distribution component is configured such that a light signal received through the inlet port with a non-periodic intensity distribution is received in the output light distribution component with a periodic intensity distribution. The period intensity distribution can have a shape that approximates a sinc function.

Abstract: A method of preparing an optical component for coupling with an optical fiber is disclosed. The method includes determining a thickness of a buffer layer formed on the optical component. The method also includes forming an anti reflective coating adjacent to the buffer layer. The anti reflective coating is formed to a thickness selected in response to the determined buffer layer thickness.

Abstract: A method of separating optical components is disclosed. The method includes obtaining a substrate structure having a plurality of optical components formed on the substrate structure. The method also includes performing a separation etch on a separation region of the substrate structure. The separation region is selected such that separating the substrate structure at the separation region separates at least one of the optical components from the other optical components.
