Performance Comparison of Single-Pump FOPA and LRA in a 16-channel DWDM Transmission System
Elektronika ir Elektrotechnika, 2019 Raman amplifiers and Fiber optical parametric amplifiers (FOPA) are positioned as the main future leading techniques for all-optical signal amplification. Distributed Raman amplifiers are known as the least noisy, but this type of amplifiers suffers from

Semiconductor optical amplifiers in avionics [PDF]
, 2011 RSOAs have been demonstrated to operate within a WDM PON architectures over a >;60nm wavelength range with large path loss capabilities. Two RSOAs enable contiguous operation over the S, C and L bands; results indicate clearly that WDM architectures ...

Novel design for noise controlled semiconductor optical amplifier [PDF]
, 2009 The use of semiconductor optical amplifiers (SOA) in optical communications networks has so far been limited due to their inherent large noise figure (NF) compared to Erbium Doped Fibre Amplifiers.

Gaussian state interferometry with passive and active elements [PDF]
, 2015 We address precision of optical interferometers fed by Gaussian states and involving passive and/or active elements, such as beam splitters, photodetectors and optical parametric amplifiers. We first address the ultimate bounds to precision by discussing

Squeezing in the audio gravitational wave detection band [PDF]
, 2004 We demonstrate the generation of broad-band continuous-wave optical squeezing down to 200Hz using a below threshold optical parametric oscillator (OPO). The squeezed state phase was controlled using a noise locking technique.
