A conductive thin film has first and second surfaces and at least one opening extending through from the first surface to the second surface. At least on one of the first and second surfaces, first and second periodic surface patterns having different period lengths are provided. The period length of the second periodic surface pattern is substantially equal to an odd integral multiple of a half of the period length of the first periodic surface pattern. With this, surface plasmon polaritons excited by the first periodic surface pattern undergo odd-order Bragg reflection by the second periodic surface pattern. As a result, the intensity of the light falling on the first surface and transmitted to the second surface through the opening is increased with high efficiency.

The guiding devices comprise a core stripe of e.g. metal of finite width embedded in a cladding such as a dielectric cladding. Particularly, in the waveguides of the invention, the complex propagation constant of the guided LR-SPP mode(s) can be dynamically adjusted by heating of the metal core leading to dissipation of heat into the surrounding dielectric material. The devices may be used in the construction of dynamic light guiding integrated components for optical telecommunication.

A light modulator has two unit devices (1,2) each using surface plasmon waves generated at the interface between thin metal films (13,14) formed respectively on prisms (11,12) and a mirror (3), in which the thin metal films are oppositely disposed with an air gap in between which can be varied by means of a piezo material. Both the transmitted light due to absorption and re-radiation, and the reflected light arising from the unit devices (1,2) appear in the outgoing light, the incident light on the next unit device, or the incident light on the mirror (3). Consequently, all light beams can be utilized as the final outgoing light beams with no loss of light. Further, the colour of light can be spatially divided, and still further, it can also be temporally divided by changing the wavelength by means of a voltage. As a result, the original light can be divided both temporally and spatially with almost no loss by combining two unit devices so configured as to re-radiate the absorbed light by the surface plasmon waves using surface plasmon and a mirror, and thus utilize both the reflected light and the transmitted light.
