Active control of surface plasmon polaritons (SPPs) by optical isomerization of an azobenzene polymer film is proposed and demonstrated in this letter. A tightly focused 532 nm laser beam was used to change the wave number of the SPPs and a separate unpolarized light source was employed to erase the change, forming one cycle of the control. The largest change of the SPPs wave number obtained in the experiments is about 0.0382K0 in the case of 54 nm thickness azo-polymer film. Validity of this method is confirmed by consistence between theoretical and experimental results.

    We demonstrate a compact, integrated device in which surface plasmon polaritons (SPPs) are injected into a passive metal waveguide. We directly excite a SPP mode at a metal-air interface using a room-temperature midinfrared quantum cascade laser which is integrated onto the microchip. The SPP...

    We report the manipulation of surface plasmon polaritons (SPPs) on a thin Au layer integrated on top of the mirror of a vertical-cavity surface-emitting laser (VCSEL). Gratings etched into the Au layer to different depths are used to couple the light into and out of the film, and to bend the...
