We consider light trapping in photonic crystals in the weak material absorption limit. Using a rigorous electromagnetic approach, we show that the upper bound on the angle-integrated absorption enhanc...
Selective thermal emission in a useful range of energies from a material operating at high temperatures is required for effective solar thermophotovoltaic energy conversion.Three-dimensional metallic ...
The optical transmission properties of two types of photonic crystals have been analyzed by using the transfer matrix method. The first one is the dielectric photonic crystal (DPC), and the second is ...
Transistor scaling alone can no longer be relied upon to yield the exponential speed increases we have come to expect from the microprocessor industry. The principle reason for this is the interconnec...
We review the simulation work for the far-field focus and dispersionless anticrossing bands in two-dimensional (2D) photonic crystals. In a two-dimensional photonic-crystal-based concave lens, the far...
We consider coherent radiative thermal conductance of a multilayer photonic crystal. The crystal consists of alternating layers of lossless dielectric slabs and vacuum, where heat is conducted only th...
In this paper, the authors review some of the recent advances in the theory of photonic crystals, drawing examples from their own work in magnetooptical and dynamic photonic crystals. The combination ...
The authors show that one-dimensional magneto-optical photonic crystals can achieve one-way total reflection. The unit cell of the crystal, which consists of two bismuth iron garnet layers with ...
The authors show that the effect of self-focusing can be controlled by exploiting spatial dispersion effects in a photonic crystal. In the positive refraction region, the critical field value fo...
Waveguiding phenomena are investigated in an inverted opal photonic crystal made of interpenetrating air spheres, coated with amorphous Ge. Here we focus on the complete gap between the 8th and the 9t...
Direct-Write Assembly of Three-Dimensional Photonic Crystals:Conversion of Polymer Scaffolds to Silicon Hollow-Woodpile Structures.
In integrated optical systems, nonreciprocal elements are indispensable devices that eliminate multi-path reflection between components. To miniaturizing these devices down to a single-wavelengt...
The authors present a general procedure that allows the design of single-mode air-core waveguides in three-dimensional photonic crystals. The procedure involves analyzing the modal profile of th...
We show theoretically that anite two-dimensional square lattice of metallic cylinders in air can be designed to have almost 100% absorptance over a wide optical wavelength range and for a wid...
