I want to design a modulator that I need to an amplifire for amplification signal after filtering.
I think you can only understand certain aspect/behaviour of EDFA through modeling in COMSOL as a device. As such EDFA is a system which is very difficult to realize in COMSOL as per my understanding.
Hi
I think its better you use Lumerical instead of comsol.
I’m trying to reproduce the acousto-optic coupling simulation in the paper Frequency–angular resolving LiDAR using chip-scale acousto-optic beam steering. LNOI(lithium niobate on insulator) is...

Hi there, I'm new to modelling with comsol. I would like to ask if it is possible for comsol to output linearly polarized (LP) modes? I tried modelling a simple single mode fiber with an enlarged...

Photo-electric effect A light particle moving towards a surface cannot (by collision) force an electron particle to move away from that surface. A light wave can instead make interference with a...

When testing devices based on ITO/ZnO/CsPbBr3/TFB/MoO3/Ag structures, I found that the current density of the device always increases sharply to 1000mA/cm2 at about 3V bias, and the device does...
