Optimized staircase profiles for diffractive optical devices made from absorbing materials.
We report on the optimization of staircase grating profiles for the case of absorbing grating materials. Using a simple numerical algorithm, we determined the grating parameters, maximizing the first-order diffraction efficiency for different numbers of staircase steps. The results show that there is a significant difference between the staircase profiles for nonnegligible and negligible absorp...

متن کاملDiffractive optical devices produced by light-assisted trapping of nanoparticles.
One- and two-dimensional diffractive optical devices have been fabricated by light-assisted trapping and patterning of nanoparticles. The method is based on the dielectrophoretic forces appearing in the vicinity of a photovoltaic crystal, such as Fe:LiNbO3, during or after illumination. By illumination with the appropriate light distribution, the nanoparticles are organized along patterns desig...
متن کاملStaircase Quantum Dots Configuration in Nanowires for Optimized Thermoelectric Power
The performance of thermoelectric energy harvesters can be improved by nanostructures that exploit inelastic transport processes. One prototype is the three-terminal hopping thermoelectric device where electron hopping between quantum-dots are driven by hot phonons. Such three-terminal hopping thermoelectric devices have potential in achieving high efficiency or power via inelastic transport an...
متن کاملFoam Materials Made from Carbon Nanotubes
1.1 What is CNT foam? Foam is a macroporous material and comes in many forms, such as polystyrene shock absorbers, dish-washing sponges, and foam board insulation. This chapter describes a technique to prepare foam materials from carbon nanotubes (CNTs). The use of a CNTmade foam as a kitchen sponge may not be a good idea, however. We of course expect the nano-carbons to have a specific functio...
