K. Ogusu et al., OBSERVATION OF NONLINEAR-WAVES IN A GRADED-INDEX PLANAR WAVE-GUIDE WITH A KERR-LIKE NONLINEAR COVER, IEICE transactions on electronics, E76C(11), 1993, pp. 1691-1694
The intensity-dependent transmission characteristics of an Ag+ <-- -->
Na+ ion-exchanged glass waveguide with a nematic liquid crystal MBBA
cover have been investigated experimentally using an Ar+ laser. It is
found that the transmission characteristics of the TE1 mode are strong
ly influenced by temperature. Optical bistability has been observed at
a particular temperature. Such the strong temperature dependence is b
elieved to be brought by an increase in ordinary refractive index of t
he MBBA cover due to temperature rise.
