Latest Patents

One of his latest patents is the Microstructure Fiber Optical Parametric Oscillator. This invention utilizes photonic crystal fibers, also known as microstructure fibers or holey fibers. The optical parametric oscillator is designed with only a few meters of microstructure fiber, positioned between a highly reflective mirror and a diffraction grating in a simple Fabry-Perot configuration. The diffraction grating is tuned to reflect a specific wavelength of the signal wave back to the microstructure fiber. In another embodiment, the microstructure fiber is placed in a ring cavity, allowing for synchronous pumping of the parametric oscillator. This technology can be implemented with free space optics or entirely with fiber optic components.

Another significant patent is the All-Fiber Photon-Pair Source for Quantum Communications. This invention describes a method for generating quantum-correlated and entangled photon pairs using parametric fluorescence in a fiber Sagnac loop. The photon pairs are generated within the 1550 nm fiber-optic communication band and are detected by a system that includes InGaAs/InP avalanche photodiodes operating in a gated Geiger mode. A generation rate exceeding 10 pairs per second is achieved, limited only by the available detection electronics. The nonclassical nature of the photon correlations in these pairs is demonstrated, making this source well-suited for fiber-optic quantum communication and cryptography networks.
