Abstract
Structures for a filter and methods of fabricating a structure for a filter. The filter is coupled to a waveguide core. The filter includes a first plurality of grating structures positioned adjacent to a first section of the waveguide core and a second plurality of grating structures positioned adjacent to a second section of the waveguide core. The first plurality of grating structures are configured to cause laser light in a first portion of a wavelength band to be transferred between the first section of the waveguide core and the first plurality of grating structures. The second plurality of grating structures are configured to cause laser light in a second portion of a wavelength band to be transferred between the second section of the waveguide core and the second plurality of grating structures.
