A recirculating loop experimentdemonstrates complete PMD compensation of the chirped Bragg grating. This simple method can beextended to deterministic PMD compensation of any components.Introduction: Pulse broadening induced by PMD is now an important limitation in long-haul opticalcommunication systems

Two types of filters are studied: a cascade of narrow-band Bragg gratings for discrete equalization of a finite number of channels and a wide-band Bragg grating performing equalization over the whole 1539 nm to 1557 nm range. In future

We also demonstrate the generation of femtosecond pulses from this source.

The theory behind this generator is based on the truncated Fourier series. Here we use this approach for implementation of an optical differentiator.

Monitoring is enabled from the nonlinear power transfer function of the loop mirror. Experimental results are provided at 40 Gb/s for three modulation formats: nonreturn-to-zero, carrier-suppressed return-to-zero, and return-to-zero. The monitor discriminates the various OSNR levels over a dynamic range of more than 25
