Experimental investigation at 10 Gb/s of the noise suppression capabilities in a pass-through configuration in SOA-based interferometric structures

“…40-Gb/s 2R regeneration has been reported [4]. Additionally, the transmission properties are good due to in-phase operation (see Fig.…”

“…In a novel approach [3], all-optical 2R regeneration can be achieved in an SOA-based interferometric structure using only the data signal, thereby making the scheme very simple and competitive in parts of the optical network, where wavelength conversion is not needed. Additionally, this regeneration scheme has been shown feasible at 40 Gb/s [4].…”

Optimal packing for cascaded regenerative transmission based on phase sensitive amplifiers

“…semiconductor optical amplifiers (SOAs) [19][20][21][22] or fibers [23][24][25][26][27][28][29] in various subsystem configurations, e.g. Mach-Zehnder [21][22] or non-linear loop mirrors (NOLMs) [24][25][26].…”

10 Gb/s-NRZ Optical 2R-Regeneration in Two-Section SOA-EA Chip

“…2R-regeneration has been demonstrated using a Michelson interferometer at 40 Gb/s [1], using interferometers with semiconductor optical amplifiers (SOA) in the arms of the interferometers [2] and also using nonlinear effects like cross phase modulation (XPM) or cross gain modulation (XGM) to perform regeneration [3]. Previous solutions [1,3] do not realize a step-like transfer function. However using the structure suggested here, combining concatenated SOA-EA (electroabsorber) sections, we may approach a step-like transfer function.…”
