| Abstract: | Based on the cascading of second-order nonlinearities, the authors propose a novel scheme for all-optical processing exploiting the tensorial nature of the second-order susceptibility. A weak phase modulated signal can efficiently modulate the amplitude of a frequency-degenerate orthogonally polarised intense beam through coherent interaction via the generated second-harmonic. Device feasibility in lithium niobate is addressed |
