### Understanding the Paraxial Gaussian Beam Formula

##### Yosuke Mizuyama September 21, 2016

The Gaussian beam is recognized as one of the most useful light sources. To describe the Gaussian beam, there is a mathematical formula called the paraxial Gaussian beam formula. Today, we’ll learn about this formula, including its limitations, by using the Electromagnetic Waves, Frequency Domain interface in the COMSOL Multiphysics® software. We’ll also provide further detail into a potential cause of error when utilizing this formula. In a later blog post, we’ll provide solutions to the limitations discussed here.

### Study the Design of a Polarizing Beam Splitter with an App

##### Abbie Weingaertner September 12, 2016

Polarizing beam splitters are optical devices used to split a single light beam into two beams of varying linear polarizations. These devices are useful for splitting high-intensity light beams like lasers as, unlike absorptive polarizers, they do not absorb or dissipate the energy of the rejected polarization state. See why creating a numerical modeling app offers a more efficient approach to analyzing and optimizing the design of these devices.

### Simulation Paves the Way for More Efficient OLED Devices

##### Caty Fairclough April 7, 2016

When it comes to creating the next generation of flat panel displays and solid-state area lighting, organic light-emitting diodes, or OLEDs, may be used to help. While recognized for its various advantages, this emerging technology suffers from some weaknesses that reduce its overall efficiency. One such example is light loss, which is partially caused by the plasmon coupling effect. Looking to reduce the effect’s prominence in OLED devices, researchers from Konica Minolta Laboratory turned to the COMSOL Multiphysics® software.
