ABSTRACT:
A plasmon enhanced near-field optical probe has an optical coupler with an end face and a metal coating forming at least one plasmon enhancement structure. An extension provides probe-to-sample separation feedback. A microscope cantilever has a lever arm with an aperture, a tip to provide tip-to-sample separation feedback, and a plasmon enhancement structure. An air bearing slider apparatus has a base, air bearing slider pads, and a metal film forming a plasmon enhancement structure about an aperture. A plasmon enhanced optical probe end cap has a socket with an entry aperture for an optical fiber and an exit aperture with a plasmon enhanced transmission structure. A positioning subsystem has a piezoelectric member that adjusts a length of the positioning subsystem, and a quadranted piezo device that adjusts a position of the positioning subsystem.
