We report a balanced optical cross-correlator based on PPKTP waveguides with sub-attosecond noise floor and more than 100 times higher timing sensitivity when compared to similar bulk optic detectors.
We present a novel, highly non-degenerate, heralded visible-telecom photon-pair source using an integrated system of nonlinear waveguides and photonic circuits. Thermo-optic modulation of the telecom single-photon-state is demonstrated for deployable quantum communication/networking systems.
A compact, all-optical, repetition rate stabilized femtosecond laser and photonic microwave generator with phase-noise -100, -140 and < -160 dBc/Hz at 100 Hz, 10 kHz and > 100 kHz, respectively, and integrated timing-jitter < 3-fs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
