Abstract :
PTS (poly-[2,4 hexadiyne-1,6 diol-bis-(p-toluene sulfonate)]) has significant potential for future applications in ultrafast all-optical switches and logic gates due to its large off-resonant third-order susceptibility and subpicosecond response time. In this work, we have made detailed measurement of spectral broadening in PTS induced by self-phase modulation at 720 to 1064 nm. The nonlinear refractive index has been determined as a function of wavelength from the spectral broadening data. The effect of group-velocity dispersion has been analyzed
