Nonlinear optics

1. Experimental measurement of third-order nonlinear optical susceptibility in organics under non-resonant and resonant conditions: substituted organic polymers, organic dyes and fullerenes; molecular engineering for structure-property relationship
2. Study of optical phase conjugation and optical limiting characteristics in Degenerate Four Wave Mixing experiments
3. Taking advantage of the optical nonlinearity in silica fibers for designing applications such as broadband pulsed and CW sources and pulse shaping in nonlinear optical loop mirror.
4. Theoretical analysis of spectral enrichment in fibers due to the combined effect of dispersion and nonlinearity and the significance of anomalous dispersion region for efficient four wave mixing.
5. Experimental measurement of Stimulated Brillouin scattering (SBS) in fibers, for the study of characteristics such as the threshold, frequency shift and requisite fiber lengths; modeling fibers with high SBS threshold.
6. Study of SBS generator and amplifier configurations for applications in Slow light.
7. Semiempirical and ab-initio calculation of frequency-dependent first hyperpolarizability for second harmonic generation in substituted benzene derivatives.
8. Study of Stimulated Raman scattering (SRS) in toluene and the threshold for anti-Stokes generation.
