On the concept of a resonant tunneling photonic nanotriode

The concept of a resonant tunneling photonic nanotriode that allows the mutual all-optical control of cross-cut light flows is developed. The concept is based on the strong resonant interaction between the quasi-localized eigenmode of nonlinear planar dielectric waveguides and incident beams. It is demonstrated that small variations of input guided wave intensities may result in deep modulation of beam reflection and transmission coefficients.
