  • Athermal arrayed waveguide grating
    Patent number: 7218815
    Abstract: An athermal arrayed-waveguide grating is disclosed and includes an input waveguide for inputting two or more optical signals from one exterior side, a grating array for separating the optical signals into different wavelengths of light, a first slab, formed with two layers and having different refractive indices from each other, for connecting the input waveguide with the grating array, a second slab for causing the different light wavelengths separated at the grating array to be imaged on an egress surface thereof, and an output waveguide array for outputting each light wavelength imaged on the egress surface of the second slab to the other exterior side in the form of a separated channel.
    Type: Grant
    Filed: July 23, 2003
    Date of Patent: May 15, 2007
    Assignee: Samsung Electronics Co., Ltd.
