All-optical tunable slow-light delays via stimulated scattering
In systems operating at ultrahigh speeds, where information is encoded with pulses of light, optical devices that eliminate the need for optical/electronic conversion of the information should be used. A new type of optical pulse delay scheme based on stimulated scattering that represents an important advance in flexibility and performance is discussed. The use of stimulated scattering to produce tunable delays represents an important advance, given that off the shelf components can be used. The slow light resonance can be tuned to any wavelength, thus allowing for operation in the S-, C-, and L-band optical communication windows.
