Large Kerr effect in bulk Se-based chalcogenide glasses.
High-speed optical communication requires ultrafast all-optical processing and switching capabilities. The Kerr nonlinearity, an ultrafast optical nonlinearity, is often used as the basic switchingExpand

Noninvasive detection of changes in membrane potential in cultured neurons by light scattering.
We report a procedure to detect electrical activity in cultured neurons by changes in their intrinsic optical properties. Using dark-field microscopy to detect scattered light, we observe an opticalExpand

Large Raman gain and nonlinear phase shifts in high-purity As 2 Se 3 chalcogenide fibers
Third-order Kerr nonlinearities and Raman gain are studied experimentally in high-purity As2Se3 optical fibers for wavelengths near 1.55 μm. Kerr nonlinear coefficients are measured to be nearly 1000Expand

Improving transmission performance in differential phase-shift-keyed systems by use of lumped nonlinear phase-shift compensation.
We show that significant improvements in transmission performance can be achieved in differential phase-shift-keyed systems by use of lumped nonlinear phase-shift compensation (NPSC). A simple deviceExpand
