Spatial eigenstates are a familiar part of optical waveguide theory. Such states enter and exit the waveguide as the same spatial state. As illustrated in Fig. 1. In the idealised case, a perfect waveguide, free of mode coupling, perturbations and ignoring chromatic dispersion, these spatial eigenstates also propagate with a single group-delay. However in reality, light propagation in multimode optical...
The applications of spatial light modulators for mode division multiplexing will be discussed, including multiplexing, characterization and wavelength switching and filtering.
The various applications of spatial light modulators in mode division multiplexing will be discussed. These include mode multiplexers and reconfigurable mode characterisation as well as for sub-systems such as wavelength selective switches, gain flattening filters and multimode pulse shapers.
We demonstrate all-optical pre-compensation of the fiber Kerr-effect on 40 Gb/s signals using a negative nonlinearity module. Tunable compensation for different DPSK formats, fiber spans and WDM channels achieves up to ≈4 dB lower BER power penalty.
An octave spanning spectrum is generated in an As2S3 taper via 77 pJ pulses from an ultrafast fiber laser. Chirp compensation allows the octave to be generated directly from the un-amplified laser output.
