Journal of Chemical Theory and Computation, 2012 Norbornenone, which has both a C═O and a C═C chromophore in a rigid bicyclic hydrocarbon framework, exhibits optical rotation (OR) an order of magnitude larger than that of similar molecules with only one of these chromophores (e.g., α-pinene). Its OR is

Nonlinear polarization rotation induced by ultrashort optical pulses in a semiconductor optical amplifier [PDF]
, 2003 We use a new rate-equation model for the propagation of sub-picosecond polarized optical pulses in a semiconductor optical amplifier (SOA). This model is based on the decomposition of the polarized optical field into TE and TM components that interact ...
