Dynamical four wave mixing in GaInP photonic crystal waveguides is demonstrated for time domain switching/demultiplexing to extract one out of 16 or 32 channels having an aggregate bit rate of 10.56Gbit/s.
In order to achieve synchronization between chaotic lasers the coupling strength must typically exceed a certain threshold. Here, we show how this threshold can be significantly reduced by adding loss that is minimized when the coupled lasers are both phase locked and synchronized. A model is developed for this loss enhanced synchronization and the calculated results are in good agreement to those...
This paper present three methods for increasing the output brightness from fiber lasers. A highly efficient method for the generation of purely radially or azimuthally polarized light within a single multimode fiber laser is investigated. This method involves the introduction of strong losses to unwanted polarizations inside the fiber laser, by introducing intra-cavity spatially variable retarder...
A unique approach for coherently adding a multiplicity of separate and independent laser distributions with intra-cavity interferometric combiners is developed. The approach which can be scalable is demonstrated with coherent addition of 25 laser distributions.
