Abstract
A broadly focused laser beam was used to investigate simultaneous excitation of multiple modes in prism and grating coupled polymer thin film optical waveguides. Concurrent coupling of two lines from different lasers through a fiber bundle was also examined. Results indicate that simultaneous multiple pathlength and multiple source sensing at the surface of thin film waveguides is feasible.
