Abstract
Optical signal devices, wavelength division multiplexer/demultiplexer optical devices, and methods of employing the same in which the core layer includes a grating and is comprised of a material whose refractive index is tuned so that the grating reflects a preselected wavelength of light. A single optical signal device can therefore be used to select a variety of wavelengths for segregation.
