An important step in designing a microstructured optical fiber is the computation and management of its dispersion curve. It is well-known that computing chromatic dispersion can be done analytically for certain geometries (e.g. step-index fibers), but no such analytical methods is known in the realm of microstructured optical fibers. Figure 1, Figure 2, and Figure 3 illustrate cross-sections of ...

Metacomposites are new class of materials with unusual properties that can be engineered using existing materials with usual properties. The unusual properties of metacomposites are derived from the structure, analogues to atomic arrangement in crystal lattice. These material exhibits unusual negative refraction type behavior to electromagnetic wave propagation and thus enables novel ...

Surface Plasmon Polaritions (SPPs), as electromagnetic waves localized at the surface of a metal, enjoy the unique properties to confine energy into sub-wavelength scale, which is beneficial for future photonic integration. However, the severe absorption caused by the metal influences the propagation distance greatly. Actually, SPPs loss can be compensated by optical parametric amplification in ...

One of the major challenges in designing µTEGs is to minimize power loss due to internal resistance (r) of Thermoelectric (TE) materials. To solve this problem we have performed simulation analysis and calculated the internal resistance of eight different TE materials. The internal resistances of these TE materials were then compared to the power generated across the copper electrode as seen in ...

In this contribution we study how a planar photonic crystal waveguide (PhCW), created by introducing a line defect in the photonic crystal, can modify the projected local density of states (LDOS) for a dipole emitter. We use the COMSOL Multiphysics® RF Module to carry out eigenvalue calculations studies on PhCW. When the dipole is in resonance with the waveguide mode, the enhancement Fp of ...

As it is known nano-sized emitters (such as atoms, quantum dots and point defects in diamonds) interaction with nano-environment leads to drastic changes of their decay rate and therefore lifetime (Purcell effect). To calculate the influence in general one needs to solve equations of quantum electrodynamics. However in weak interaction limit these emitters can be considered as point electric ...

In this study, COMSOL Multiphysics® software was applied to the investigation of the electromagnetic behavior of an optical crystal submitted to the magnetic field generated by electric current in a near positioned metallic conductor. Moreover, the influence of a ferromagnetic apparatus (magnetic concentrator) on the magnetic field acting upon the crystal was investigated. Three cases were ...

The emergence of electromagnetic metamaterials has given rise to a variety of fascinating applications, including the perfect lens and the optical cloaking device. For a long time the study of the properties of metamaterials was limited to normal incidence only. However, it is extremely important to know the behavior of metamaterials especially in the area of imaging. In this paper, we use ...

Laser anemometers based on application of Doppler Effect have been developed and are used in-flight, on aircrafts for measurement of air flow parameters, mainly its speed versus the airplane. The air speed measurements are vital for safe flights. The main basic idea of Doppler techniques consists in measuring the frequency of scattered light. In this paper, we propose a study of a laser Doppler ...

The use of plasmonic effects to dramatically enhance the electromagnetic field near the surface of a metallic nanostructured surface has grown into a large research area in the effort to take advantage of the surface enhanced field. In this paper the electromagnetic field near a nano-sized truncated spherical cavity embedded in a gold substrate is investigated and modeled in 3D with COMSOL ...
