Linear and nonlinear dispersion compensation of short pulses using midspan spectral inversion

- Short Pulses in Linear and Nonlinear Media

We consider the evolution of ultra-short optical pulses in linear and nonlinear media. For the linear case, we first show that the initial-boundary value problem for Maxwell's equations in which a pulse is injected into a quiescent medium at the left endpoint can be approximated by a linear wave equation which can then be further reduced to the linear short-pulse equation. A rigorous proof is g...

Adaptive all-order dispersion compensation of ultrafast laser pulses using dynamic spectral holography

The time-varying dispersion of ultrafast laser pulses can be self-adaptively stabilized using real-time dynamic spectral holography in semiconductor photorefractive quantum wells. Dispersion of all orders is compensated by forming a dynamic spectral-domain hologram of a signal pulse ~that has a time-varying dispersion! referenced to a stable clock pulse. The hologram is read out using forward-s...

Chromatic Dispersion Compensation by Signal Predistortion: Linear and Nonlinear Filtering

Chromatic dispersion is one of the most significant impairments in long-distance fiber-optical communications. Electrical domain compensation of optical chromatic dispersion by signal predistortion using digital processing is investigated with two different approaches: using a linear digital FIR compensating filter and using a nonlinear filter based on a look-up table (LUT). The linear compensa...
