AN OPTICAL DEVICE FOR DISPERSION COMPENSATION |
摘要 |
An optical device ( 2 ) having a number of waveguides ( 12 ), an input port ( 6 ) coupled to the waveguides ( 12 ) such that light incident on the input port ( 6 ) is split for propagation on the waveguides, and an output port ( 10 ) receiving light propagated on the waveguides ( 12 ) at a point on an output plane of incidence. The waveguides ( 12 ) induce respective delays in the propagated light to induce a wavelength dependent group delay. Delays between adjacent waveguides are chosen to be non-constant, to introduce quadratic, cubic or higher-order phase differences between different waveguides. Applications include dispersion compensation, pulse compression, and passband broadening in arrayed waveguide grating multiplexers and demultiplexers. |
