Semiconductor Optical Amplifiers and their Application for All Optical Wavelength Conversion
All optical networks and switches are envisioned as a solution to the increasing complexity and power consumption of today’s communication networks who rely on optical fibers for the transmission of information but use electronics at the connecting points on the network (nodes) to perform the switching operation. All optical networks, in contrast, will use simple signalling methods to trigger a...
متن کاملAll-Optical Wavelength Conversion at Bit Rates Above 10 Gb/s Using Semiconductor Optical Amplifiers
This work assesses the prospects for high-speed alloptical wavelength conversion using the simple optical interaction with the gain in semiconductor optical amplifiers (SOA’s) via the interband carrier recombination. Operation and design guidelines for conversion speeds above 10 Gb/s are described and the various tradeoffs are discussed. Experiments at bit rates up to 40 Gb/s are presented for ...
متن کاملUltrafast all-optical wavelength conversion based on (3+1)-D optical soliton dragging interaction
Spatial dragging of optical solitons is an asymmetric interaction in which a weak signal soliton propagating at a tilted angle can drag an initially overlapping strong pump soliton with orthogonal polarization to the side, thus missing a spatial aperture at the output. A novel ultrafast all-optical wavelength converter based on (3+1)-D soliton dragging interaction between frequency shifted soli...

متن کاملNegative Feedback Semiconductor Optical Amplifiers and All-Optical Triode
The field of optical communications is moving toward the realization of photonic networks with wavelength division multiplexing (WDM) utilizing the full bandwidth of optical fibers. Conventionally, an erbium-doped fiber amplifier (EDFA) and a semiconductor optical amplifier (SOA) are used for amplifying an optical signal in optical communications. SOAs can contribute to this and offer the key a...
