The refractive indices are determined experimentally by photoreflectance spectroscopy and prism-coupler method as a function of their composition.

The fluctuations in the linear birefringence, including temperature and pressure induced ones, that affect the measurement of the NPR are successfully removed in a passive way by using a double pass of the fiber under test with a Faraday mirror at the end of the fiber. This method provides excellent switching stability over long term period when applied to a wavelength converter.","PeriodicalId":314041,"journal":{"name":"2000 2nd International Conference on Transparent Optical Networks.

Common methods to generate sub-picosecond, single-cycle electromagnetic pulses evoke great interest and there is an excitation of a biased semiconductor or an electro-optic crystal with a femtosecond light pulse among them. It needs a detailed investigation of the propagation properties of ultrashort pulse beams scattered by interfaces with time-varying properties. In this paper we obtain integral operators that describe in time domain in the 3-D case an interaction of complex electromagnetic signals with the flat interface between dielectric media when the medium in one of the two halfspaces changes its permittivity and acquires a conductivity.","PeriodicalId":314041,"journal":{"name":"2000 2nd International Conference on Transparent Optical Networks.
