Abstract
A new resonance breaking in-fiber switch as an all-optical network
component is investigated and presented. A transient grating is applied to
break the transverse resonance of the fundamental waveguide mode and the
power coupled into the higher order propagating mode is computed using
coupled mode theory (CMT). The coupling of the modes with the grating
forming beams in the evanescent region of the waveguide is investigated with
four wave mixing (FWM). High conversion efficiency is calculated in the case
of perfect phase matching at communication wavelength 1550 nm. The
conversion efficiency of the proposed structure is considered in terms of
third-order nonlinear susceptibility, and the effect of design and tuning
parameters are investigated for grating forming geometry and laser beam
intensity, respectively.
