We confirmed that an optical frequency-modulated signal can be transmitted through surface plasmon polaritons (SPPs) in a sample consisting of a gold film with a light/SPP coupler (coupling and decoupling gratings).
We describe the use of a deformable membrane mirror for fast and flexible focus control in a commercial confocal microscope. En-face and oblique imaging over a 55 μm focal range has been demonstrated.
Polycrystalline ferroelectric modified lead titanate thin films have been deposited by pulsed laser deposition and annealed for pyroelectric infrared detection. The deposited thin films have been characterized for the temperature dependence of their pyroelectric parameters.
A bonding technique, capable of sub-micron and finer alignment accuracy, has been developed for electronics-optics heterogeneous integration applications. The technique is based on the principle of misalignment self-correction using bump (convex) and hollow (concave) elements, to align one die (i.e. a chip) to another one (i.e. a substrate) during the stacking process. Conductive hollow pad and Au...
The Casimir force arising from quantum fluctuations could become the dominant interaction in silicon micromechanical devices under the appropriate conditions. The measured force is distinct from the pairwise summation of van der Waals forces.
Three-dimensional patterning of gold nano-particles on SiO2 and Si substrates is performed by ion-beam lithography with 15–20 nm resolution. Realization of an on-demand achiral and chiral modifications of nano-structures are demonstrated. Simulations of optical properties of the obtained nano-architectures reveal the possibility to tailor the field enhancement both in the spatial and spectral domains,...
High-frequency electromagnetic-field simulation HFSS has been performed on sub-millimeter scale split-ring resonator (SRR) metamaterials to propose electrostatically tunable THz frequency filters with integrated RF-MEMS variable capacitors and switches.
