Jun 15, 2017 · If the cavity mirrors are not perfectly aligned, the laser won't work. Learn how to predict laser stability with the ray-tracing capabilities of COMSOL Multiphysics®.

This is an example of a Fabry-Perot cavity, the simplest optical resonator structure. It is a classical problem in optics and photonics. Two methods are shown for computing the Q-factor. The losses in …

Typically, lasers are produced by a laser cavity or optical cavity containing a set of mirrors, a gain medium, and possibly some other optical components such as prisms or lenses. Stability analysis of …

Computing Q Factors and Resonant Frequencies of Cavity Resonators Application ID: 9618 A classic benchmark example in computational electromagnetics is to find the resonant frequency and Q …

Introduction By properly arranging a set of mirrors, we can create passive optical resonators that are of great use to probe and manipulate light or to build lasers. The textbook example of a free space …

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 …

Aug 14, 2018 · An optical ring resonator (left) exhibits an effect similar to that of a whispering gallery (right), but with light waves instead of sound. Right: The whispering gallery at St. Paul’s Cathedral in …

Mechanical stress of the cantilever leads to refractive index change which in turn is observed as a shift of the optical resonance in the Bragg grating reflection spectrum (see figure 2 with 1μN applied force …

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 …
