Abstract
The Double Phase Conjugated Mirror (DPCM)1 and the Double Colour Pumped Oscillator (DCPO)2 are particularly interesting devices for reconfigurable optical interconnects2,3,4,5. In a DPCM two mutually incoherent pump beams (at nearly identical wavelengths) incident on the opposite faces of a photorefractive (PR) crystal share a common grating which diffracts them into the phase conjugated of the opposite one. When the wavelength difference of the interacting beams is important (larger than the grating selectivity), they can still induce a common grating (DCPO). Recently DPCM has been observed in InP:Fe6 and GaAs:EL27 at 1.06 μm and DCPO has been achieved in InP:Fe using 1.06 and 1.32 μm wavelengths8.
