Abstract:

Large linear refractive index birefringence, strong dichroic behavior, and highly anisotropic X3 have been observed for a uniaxially oriented poly 2, 5-dimethoxy paraphenylene vinylene film. A subpicosecond time-resolved degenerate four-wave mixing study revels an unusual behavior. Along the draw direction X3 is complex with a negative real part and has a response time that is longer than the optical pulse resolution. In contrast, X3 along the transverse direction is largely real and positive. Its response time is much faster, and is limited by the laser pulse width. JES
