Sentences with phrase «optical nonlinearity»

Due to the small extent of optical nonlinearity in naturally occurring materials, high light intensities and long propagation distances in nonlinear crystals are typically required to produce detectable nonlinear optical effects.

«Optical nonlinearity record: Discovery offers a «game - changer» for photonics applications.»

The grating can be tuned so that the optical nonlinearity can be turned on and off on - demand.

At a slightly different frequency, the bandgap will completely inhibit (or suppress) the optical nonlinearity.

This will greatly enhance the optical nonlinearity.

We showed that we can dramatically enhance the optical nonlinearity so that it can be made even more useful.

We think this approach can be generalized to many other optical nonlinearities.»

Boyd, his PhD student at Ottawa, M. Zahirul Alam, and then research associate Israel De Leon (currently a professor in Monterrey, Mexico) were able to improve on the previous record for optical nonlinearities by a factor of 100.

Then, by applying an electrical field across the nanobelt, Agarwal and his colleagues were able to introduce optical nonlinearities to the system that enable a signal mixing output that was otherwise zero.

Not exact matches

Including emission along a path (Schwarzchild's equation), a flux will approach saturation as the optical thickness becomes large over scales where the temperature variation is small; at smaller optical thicknesses, the temperature distribution may vary and larger temperature variations make the nonlinearity of the Planck function important, but over short distances, the temperature variation can be approximated as linear and the associated Planck function values can be approximated as linearly proportional to distance for small temperature changes, so the flux will approach an asymptotic value as a hyperbolic function (the difference between the flux and the saturation value of the flux will be proportional to 1 / optical thickness per unit distance (assuming isotropic optical properties (or even somewhat anisotropic properties), it will have that proportionality for all directions and thus for the whole flux across an area).
