A method of forming and a random Distributed Bragg Reflector (DBR) is disclosed. The random DBR includes a substrate and a plurality of alternating layers of lattice-matched nanoporous GaN (NP-GaN) and GaN formed on a top surface of the substrate, wherein at least one of the alternating layers has a thickness of &#x3bb;/4n and an adjacent one of the alternating layers does not have a thickness of &#x3bb;/4n, wherein &#x3bb; is a wavelength of incident radiation and n is the refractive index of a particular layer of the plurality of alternating layers.

A method and system for determining a photon statistics of a light source using an unbalanced beam-splitter is disclosed. The method includes collecting data for photon counts for a first output path and a second output path by a first detector and a second detector, respectively, for a first time period, a first power level, and a first characteristic and collecting data for photon counts for the first output path and the second output path by the first detector and the second detector, respectively, for a second time period, a second power level, and a second characteristic; and processing outputs of the first and the second detector to determine the photon statistics.
