Ultralow phase noise microwave generation with an Er:fiber-based optical frequency divider
, 2011 We present an optical frequency divider based on a 200 MHz repetition rate Er:fiber mode-locked laser that, when locked to a stable optical frequency reference, generates microwave signals with absolute phase noise that is equal to or better than ...

Analytical approach of Brillouin Amplification over threshold
, 2017 We report on an accurate closed form analytical model for the gain of a Brillouin fiber amplifier that accounts for material loss in the depleted pump regime.

Absolute calibration of fiber-coupled single-photon detector
, 2014 We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and can be implemented with standard-optic components, it can be realised in ...

Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber
We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%
