Determination of nonlinear refractive index in a Ta2O5 rib waveguide using self-phase modulation.
Self-phase modulation has been observed for ultrashort pulses of wavelength 800nm propagating through a 1 cm-long Ta2O5 rib waveguide. The associated nonlinear refractive index n2 was estimated to be 7.23x10-19 m2/W, which is higher than silica glass by more than one order of magnitude. Femtosecond time of flight measurements based on a Kerr shutter configuration show that the group velocity di...
متن کاملRefractive index determination
The central focal masking ("dispersion staining") technique is convenient and effective for determining the refractive index of a microfragment by the immersion method and for distinguishing between minerals in an immersion mount. For most microscopes the only modification needed is the installation of a small opaque dot at or near the focal point of the medium power objective. White light illu...

based on the differential phase modulation between the two orthogonal polarization (TE and TM) modes of guided light beams of optical waveguide.1–4 We have developed such a type of RI sensor using a slab optical waveguide (SOWG) with a prism coupler.5 This type of RI sensor allows us to use a relatively simple optical configuration, compared with other RI sensors using a planer optical waveguid...
متن کاملDetermination of Refractive Index and Confinement Losses in Photonic Crystal Fibers Using FDFD Method: A Comparative Analysis
In this paper, we present a comparative numerical analysis to determine the refractive index of photonic crystal fibers (PCFs) by using FDFD method and used the results to evaluate the confinement losses of PCFs by considering the effects of air-hole rings in the cladding. It is shown that by increasing the wavelength, the imaginary part of refraction index rises, resulting in increase of conf...
متن کاملDetermination of Gain and Phase Margins in Lur’e Nonlinear Systems using Extended Circle Criterion
Nonlinearity is one of the main behaviors of systems in the real world. Therefore, it seems necessary to introduce a method to determine the stability margin of these systems. Although the gain and phase margins are established criteria for the analysis of linear systems, finding a specific way to determine the true value of these margins in nonlinear systems in general is an ongoing research i...
