Omnidirectional reflector using one-dimensional dispersive photonic heterostructure

We present theoretical design for omnidirectional reflector (ODR) using one-dimensional photonic heterostructure. With the help of transfer matrix approach, we present a simple design to achieve the ODR at a desired wavelength range of interest using a high refractive index material which is dispersive at that wavelength range. Taking material combinations of SiO2 and GaSb as low and high index medium a perfect ODR is designed in the 1480–1680 nm wavelength region.
