Detection of Optically Active Molecules by Means of Integrated Optical
Devices
Silvia Mittler
Optical active material can turn the polarisation direction of a light beam. The
turning strength depends on the concentration, the interaction length between
the light and the material as well as its optical activity, which shows a
dispersion behaviour. In this current project integrated optical devices will be
used to measure the optical activity. The polarisation direction defined by the
propagating modes, TE or TM modes, will be used to measure the optical activity
of molecules located within the guided field.
Coupling a pure TE mode into the waveguide and placing optically active molecules within the field
of the propagating wave will yield a mixed mode structure of both TE and TM contributions after an appropriate propagation length.
