Fiber Simulator

The transmission speed of optical waveguides is superior to microwave waveguides because optical devices have a much higher operating frequency than microwaves, enabling a far higher bandwidth. Single-mode step-index fibers are used for long-haul (even transoceanic) communication, ... 詳細を見る

Computing the Scattering of Light from a Rough Surface with a Metal Coating

These examples demonstrate how to compute the total reflection, transmission, and absorption of light when a plane wave, at optical wavelengths, is incident upon a dielectric slab with a thin metal coating. Three examples are included that show: An optically flat slab A slab with a ... 詳細を見る

Photonic Crystal

Photonic crystal devices are periodic structures of alternating layers of materials with different refractive indices. Waveguides that are confined inside of a photonic crystal can have very sharp low-loss bends, which may enable an increase in integration density of several orders of ... 詳細を見る

Dielectric Slab Waveguide

A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step-index fiber. This model solves for the effective index and fields of a dielectric slab waveguide and compares the solution to analytic results. 詳細を見る

Single Mode Fiber-to-Fiber Coupling

Focusing a laser beam onto the tip of a single mode fiber is a common way to couple light. To achieve a good coupling efficiency, the spatial mode of the light field has to match the spatial model of the fiber. In this model, we use the Beam Envelopes Method to compute a small free space ... 詳細を見る

Time to Frequency FFT Analysis of a Distributed Bragg Reflector

This model demonstrates how to setup a Time Domain to Frequency FFT study for a distributed Bragg reflector (DBR) structure. The results agree well with the results of a regular Frequency domain study. 詳細を見る

Whispering Gallery Mode Resonator

Dielectric microspheres can support whispering gallery modes with high optical quality factors. This model illustrates how to compute the different eigenmodes and resonance frequencies. The resonance frequencies are either filtered by their spatial localization in the resonator or by ... 詳細を見る

Directional Coupler

Two embedded optical waveguides in close proximity form a directional coupler. The cladding material is GaAs and the core material is ion-implanted GaAs. The waveguide is excited by the two first supermodes of the waveguide structure - the symmetric and antisymmetric modes. Two numeric ... 詳細を見る

Stress-Optical Effects in a Photonic Waveguide

Planar photonic waveguides in silica (SiO2) have great potential for use in wavelength routing applications. The major problem with this type of waveguide is birefringence. Anisotropic refractive indices result in fundamental mode splitting and pulse broadening. The goal is to minimize ... 詳細を見る

Focusing Lens

Optical lenses of millimeter size cannot easily be analyzed with the Electromagnetic Waves, Frequency Domain interface on standard workstations due to the large number of finite element mesh elements required. This model explains how the Electromagnetic Waves, Beam Envelopes interface ... 詳細を見る
