Surface relief structures are optically inscribed onto azobenzene containing thin films. We present a brief review of the technique and results. The films act either as optical waveguides of as substrates upon which thin gold films are deposited to support surface plasmon waves. Multiple gratings are inscribed to act as optical couplers and Bragg gratings. Here, we report on the amplitude and phase changes that occur when the incident light is resonantly coupled into waveguide or surface plasmon modes. We illustrate the method of obtaining the dispersion curve of the device. The effects on amplitude are readily observed in the transmission or reflection spectra. In addition, since the structures can be made such that the resonant TE and TM modes to be well separated, we can measure the phase changes of the transmitted or reflected beams near resonance. A simple device showing polarization to wavelength modulation encoding is presented.
