Polarization conversion spectroscopy of hybrid modes.
Enhanced polarization conversion in reflection for the Otto and Kretschmann configurations is introduced as a new method for hybrid-mode spectroscopy. Polarization conversion in reflection occurs when hybrid modes are excited in a guiding structure composed of at least one anisotropic medium. In contrast to a dark dip, in this case modes are associated with a peak in the converted reflectance spectrum, increasing the detection sensitivity and avoiding confusion with reflection dips associated with other processes, such as transmission.
