Wave Optics

Certain applications require these calculations…

 
Certain applications require that light should be viewed as a wave. This mainly applies if there are apertures, blocks, and other obstructions in the light beam path. Diffractions cannot be neglected, and traditional ray tracing would provide insufficient or even incorrect data. An electromagnetic field with necessary amplitude and phase should be modeled instead. The complexity and calculation time increase somewhat.
 

If the light is also propagated through sub-wavelength structures, rigorous simulations are needed where the vectorial nature of light is taken into consideration.

 

We at Alfa Exx often work with diffraction spreading, from UV to IR radiation.
Examples of applications
 
1. reflection in gratings
2. propagation in waveguides
3. spatial filtration in apertures and
4. diffraction in slot openings
