24 Jun 2003 | Journal: | Phys. Rev. Lett. 91, 173901 (2003). | Subject: | Optics; Chemical Physics | physics.optics physics.chem-ph | Abstract: | We report the observation of sum-frequency signals that depend linearly on an applied electrostatic field and that change sign with the handedness of an optically active solution. This recently predicted chiral electro-optic effect exists in the electric-dipole approximation. The static electric field gives rise to an electric-field-induced sum-frequency signal (an achiral third-order process) that interferes with the chirality-specific sum-frequency at second-order. The cross-terms linear in the electrostatic field constitute the effect and may be used to determine the absolute sign of second- and third-order nonlinear optical susceptibilities in isotropic media. | Source: | arXiv, physics/0306172 | Services: | Forum | Review | PDF | Favorites |
