In this model, two concave mirrors are placed at a distance and a ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the predefined computation time has passed if the laser cavity is ... En savoir plus
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser. The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. ... En savoir plus
When the Vdara hotel first opened in Las Vegas, visitors relaxing by the pool would experience intense periods of heat at certain times of the day, at certain times of the year. This intense heat was caused by the reflection of solar radiation from the curved, reflective surface on the ... En savoir plus
This tutorial shows how to set up a ray release based on the incident electric field at a boundary. First the Electomagnetic Waves, Frequency Domain interface is used to solve for the electric field of a plane wave. Then rays are released with initial intensity and polarization matching ...

In this model, two flat end mirrors are placed at a distance and a spherical lens is inserted in the middle of the cavity. A ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the ... En savoir plus
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... En savoir plus
The Rowland circle is a circle of radius R that lies tangent to a concave curved diffraction grating of radius 2R. If the entrance slit of incoming light is positioned on this circle, then rays reflected by the grating will be focused at various points along the same circle based on ... En savoir plus
In this model a plane wave with circular polarization is reflected off an interface between air and glass. The model demonstrates three different ways of defining this problem. The first part shows how to define user-defined port mode fields. The second part uses the predefined circular ... En savoir plus
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. En savoir plus
In this model, an eigenfrequency analysis is performed to give a bandgap analysis of a 1D multilayer photonic crystal extending to infinity in +/- y direction. We perform the bandgap analysis for three different cases of material properties, as discussed in Chapter 4 of Ref. 1. Case ... En savoir plus
