Realization of an all-optical zero to π cross-phase modulation jump [PDF]
, 2009 We report on the experimental demonstration of an all-optical π cross-phase modulation jump. By performing a preselection, an optically induced unitary transformation, and then a postselection on the polarization degree of freedom, the phase of the ...

A millimetre wave phase shifter using a 40GHz hybrid mode locked laser [PDF]
, 2008 In this paper, electrical injection locking of a modelocked laser is used to create a millimetre wave phase shifter. The phase shift is measured directly using a vector network analyzer enabling straightforward characterization of such systems.
