Hybrid seeded femtosecond optical parametric amplifier
Optics Express, 2005 We propose and demonstrate a novel hybrid seeded optical parametric amplifier (OPA) that incorporates an external CW seeding at signal wavelength in the first stage and difference-frequency mixing between the idler and pump in the second stage. By using a germanium plate to block the CW seeding background, spectrally and temporally clean signal pulses ...

Design of Hybrid Optical Amplifiers for High Capacity Optical Transmission [PDF]
ETRI Journal, 2002 This paper describes our design of a hybrid amplifier composed of a distributed Raman amplifier and erbiumdoped fiber amplifiers for C- and L-bands. We characterize the distributed Raman amplifier by numerical simulation based on the experimentally measured Raman gain coefficient of an ordinary single mode fiber transmission line.

Optimization of hybrid amplifier parameters for improved optical link performance
Optical and Quantum Electronics, 2021 Abstract In this manuscript, the gain of the EDFA-Raman hybrid optical amplifier (HOA) is maximized using a popular nature inspired Whale Optimization Algorithm (WOA). The dominating parameters of HOA, length of Raman amplifier and EDFA and its pump powers are optimized to get the maximum possible gain.

Polarization resolved four-wave-mixing-based measurement in bulk material semiconductor optical amplifier [PDF]
, 2006 The anticipated growth in demand for bandwidth leads to the development of all-optical signal processing techniques at ever increasing data rates. One possible candidate to achieve the required performance is the semiconductor optical amplifier (SOA). It
