Abstract
Controlling, guiding, manipulating, and circuiting light and performing surface-enhanced spectroscopy in a medium comprising plasmonic nanomaterials via the excitation of plasmon modes in the materials. The plasmonic nanomaterials are based on metal films with or without arrays of nanoholes and/or on metal nanowires and/or spheroids. Also devices and methods employing such plasmonic nanomaterials.

A method for optically controlling characteristics of an optically thick metal film, the method comprising the steps of:
- providing a film with an optical nonlinearity but not having fabricated periodic perforation;
- and
- directing at the film at least two control light beams at angles ±Θ with respect to normal;
- thereby inducing light transmittance through the film, the induced light transmittance having two or more stable states, any of which states may be induced.
A method for optically controlling characteristics of an optically thick metal film, the method comprising the steps of:
- providing a film with an optical nonlinearity but not having fabricated periodic perforation by providing non-periodic nanoholes to the film;
- and
- directing at the film at least two control light beams at angles ±Θ with respect to normal;
- thereby inducing light transmittance through the film.
