Absorbance-modulation optical lithography.

We describe a new mode of optical lithography called absorbance-modulation optical lithography (AMOL) in which a thin film of photochromic material is placed on top of a conventional photoresist and illuminated simultaneously by a focal spot of wavelength lambda1 and a ring-shaped illumination of wavelength lambda2. The lambda1 radiation converts the photochromic material from an opaque to a tr...

Renormalization of optical excitations in molecules near a metal surface.

The lowest electronic excitations of benzene and a set of donor-acceptor molecular complexes are calculated for the gas phase and on the Al(111) surface using the many-body Bethe-Salpeter equation. The energy of the charge-transfer excitations obtained for the gas phase complexes are found to be around 10% lower than the experimental values. When the molecules are placed outside the surface, th...

Realistic Silver Optical Constants for Plasmonics

Silver remains the preferred conductor for optical and near-infrared plasmonics. Many high-profile studies focus exclusively on performance simulation in such applications. Almost invariably, these use silver optical data either from Palik's 1985 handbook or, more frequently, an earlier Johnson and Christy (J&C) tabulation. These data are inconsistent, making it difficult to ascertain the relia...

Plasmonics meets far-field optical nanoscopy.

Plasmonics and near-field optical nanoscopy both deal with expanding optics into the subwavelength regime. However, these two fields have so far followed parallel paths of development and only recently have researchers started to explore combinations of their concepts with potential synergy. In this Perspective, we provide an up-to-date summary of the successful combinations reported and give i...

Plasmonics with a twist: taming optical tornadoes on the nanoscale

This chapter discusses a hydrodynamics-inspired approach to trap and manipulate light in plasmonic nanostructures, which is based on steering optical powerflow around nano-obstacles. New insights into plasmonic nanofocusing mechanisms are obtained by invoking an analogy of the ‘photon fluid’ (PF). By proper nanostructure design, PF kinetic energy can be locally increased via convective accelera...
