Nonlinear optical switching matrix
Optics Letters, 2003 We show that nonlinear directional couplers with variable coupling coefficients can be used to compose a special kind of switching matrix. The switching matrix can be controlled by the signal itself or by a strong pump. Light routing is realized by adjustment of the power of the signal or the pump.

Controlling the phase of a light beam with a single molecule
, 2011 We employ heterodyne interferometry to investigate the effect of a single organic molecule on the phase of a propagating laser beam. We report on the first phase-contrast images of individual molecules and demonstrate a single-molecule electro-optical ...

Coexistence of Josephson oscillations and novel self-trapping regime in optical waveguide arrays [PDF]
, 2006 Considering the coherent nonlinear dynamics between two weakly linked optical waveguide arrays, we find the first example of coexistence of Josephson oscillations with a novel self-trapping regime.

Equivalent random analysis of a buffered optical switch with general interarrival times [PDF]
, 2009 We propose an approximate analytic model of an optical switch with fibre delay lines and wavelength converters by employing Equivalent Random Theory. General arrival traffic is modelled by means of Gamma-distributed interarrival times.

Crosstalk-free Conjugate Networks for Optical Multicast Switching
, 2006 High-speed photonic switching networks can switch optical signals at the rate of several terabits per second. However, they suffer from an intrinsic crosstalk problem when two optical signals cross at the same switch element.
