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.
