Low-loss polymer materials incorporating fluorinated compounds have been utilized for the investigation of various functional optical devices useful for optical communication and optical sensor systems. Since reliability issues concerning the polymer device have been resolved, polymeric waveguide devices have been gradually adopted for commercial application systems. The two most successfully c...

Mo/Si multilayer mirrors were exposed to deuterium ions with well-defined energies in order to gain insight into the effects of Extreme UV light driven plasma generation on reflective elements in commercial lithography equipment. Post-irradiation analysis by Rutherford Backscattering Spectrometry (RBS) showed erosion of both Mo and Si layers for the highest energy (50 eV/D) and exposure time (5...

scanning near-field optical microscopy (snom) is a member of scanning probe microscopes (spms) family which enables nanostructure investigation of the surfaces on a wide range of materials. in fact, snom combines the spm technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. in this paper, a qualified overview of ...

Optical fibers, the enablers of the Internet, are being used in an ever more diverse array of applications. Many of the rapidly growing deployments of fibers are in high-power and, particularly, high power-per-unit-bandwidth systems where well-known optical nonlinearities have historically not been especially consequential in limiting overall performance. Today, however, nominally weak effects,...

The ability to uniquely identify an object or device is important for authentication. Imperfections, locked into structures during fabrication, can be used to provide a fingerprint that is challenging to reproduce. In this paper, we propose a simple optical technique to read unique information from nanometer-scale defects in 2D materials. Imperfections created during crystal growth or fabricati...

Results for the effects of on materials for a new laser-driven accelerator are presented. Various optical and laser materials are compared. While Si and fused c-SiO appear ideal for sub-bandgap laser wavelengths, other interesting candidates include certain fluorides and compound semiconductors.

We consider some nonlinear phenomena in metamaterials with negative refractive index properties. Our consideration includes a survey of previously known results as well as identification of the phenomena that are important for applications of this new field. We focus on optical behavior of thin films as well as multi-wave interactions.

Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields. A large portion of these properties find their connection to optics and photonics. In the context of ...
