Increased light scattering have been found to improve the short-circuit current of photovoltaic devices. In this paper we have tried to optimize the dimensions of ZnO nanorods to achieve this. Scattering efficiency of these nanorods was evaluated by solving Maxwell’s electromagnetic equation in the nanorods and surrounding perovskite using COMSOL Multiphysics software. For evaluation of ...
Designers of electro-optic modulators and related devices often use separate tools to study the optical and electrical portions of the device. The flexibility of COMSOL Multiphysics makes it possible to construct unified models of EO phenomena including realistic waveguide profiles and anisotropic material properties. We demonstrate the use of the RF Module to compute both RF and optical ...

In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and sensitivity of these fibers are estimated using COMSOL Multiphysics®, and compared with the theoretical values ...

We used COMSOL Multiphysics® software to calculate the mode distribution by numerically solving the wave equation in the fiber. We consider the transmission from the fiber 1 to the fiber 2. In the first case, the transmission was calculated as function of the wavelength of the propagated mode. We observed that the transmission for the fundamental mode on fiber 2 has a maximum at the same ...

In this paper, all optical microring resonator based on Lithium Niobate on Insulator (LNOI) has been proposed. LNOI has high refractive index contrast and also show better electro-optic & acousto-optic effects. The optical ring resonator resonates when the optical path-length of the ring is equal to the integral multiple of the wavelength. The Wave Optics Module of COMSOL Multiphysics® software ...

Surface plasmon resonance (SPR) sensors proved themselves as a promising device for many kinds of applications such as optical biosensing, binding constant determinationor nanofilm thickness measurements. Here we simulate using COMSOL Multiphysics® the light-polaritons coupling for the two most commonly used SPR setups: Attenuated total reflection (Kretschmann configuration) and diffraction ...

Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The Electromagnetic Waves (emw) interface of COMSOL Multiphysics® was extensively used during the analysis of all our ...
