Three-dimensional simulation of guided-wave second-harmonic generation in the form of coherent Cerenkov radiation
Abstract:
We implement a direct three-dimensional calculation of Cerenkov-radiation-type frequency doubling in an optical channel waveguide by using a finite-element guided-beam simulator. The simulator can predict an optimum configuration and the conversion efficiency of miniaturized frequency doublers that utilize guided-to-radiation-mode interactions in nonlinear channel waveguides. Computed results are shown for blue-light generation through the frequency doubling in a proton-exchanged MgO:LiNbO(3) channel waveguide.

Electromagnetic Waves in Matter
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore, the...
Propagation of Waves
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
