Article Synopsis
- A new optical transmission system is introduced that successfully shows mode division multiplexing capabilities.
- The system features a mode multiplexer and demultiplexer using a programmable liquid crystal panel, along with a prototype few-mode fiber and advanced processing algorithms.
- Two data streams, each at 100 Gb/s, were transmitted and after covering 40 km, the received signal quality was found to be adequate for error correction.
Programmable spectral phase modulation of femtosecond pulses by use of a nonpixelated spatial light modulator is reported. This light valve, based on the optical addressing of a continuous layer of liquid crystal, allows the operation of spectral phase modulation when optical frequency components are spatially dispersed within a grating-and-lenses pulse-shaping apparatus. Characterization and feedback control of this device were determined by use of spectral interferometry.

Our filter has a large group-delay range that extends over 3 ps and a 30% diffraction efficiency over 150 THz. Experiments were conducted on a kilohertz chirped-pulse amplification laser chain capable of generating 30-fs pulses without additional pulse shaping.
