Abstract
A photonic device is provided. The photonic device may include an input region and a dispersive region optically coupled with the input region. The dispersive region may include a first material and a second material anisotropically distributed to form a plurality of interfaces that each correspond to a change in a refractive index of the dispersive region. The plurality of interfaces may collectively structure the dispersive region to generate an output optical signal from an input optical signal. The photonic device may also include an output region, optically coupled with the dispersive region. The plurality of interfaces may form a material interface pattern in the dispersive region that is characterized by a defect distribution to introduce one or more spectral artifacts into the output optical signal that collectively define a unique spectral signature of the photonic device.
