single fiber endoscopy Topics by Science.gov

This enables the high performance of single mode fiber devices to be attained in multimode fibers. We report an experimental proof of concept by using photonic crystal fiber techniques to make the transitions, demonstrating a multimode fiber filter with the transmission spectrum of a single mode fiber grating.

APS 2008 APS March Meeting Session Index MAR08

By splitting a single photon and subsequent state transfer, we separate the generation of entanglement and its storage, enabling efficient scaling for high fidelity quantum communication. After a programmable delay, chosen at 1us, the stored entanglement is mapped back into photon modes with an overall efficiency of 17{\%}.
