Optiwave software can be used in different industries and applications, including Fiber Optic Communication, Sensing, Pharma/Bio, Military & Satcom, Test & Measurement, Fundamental Research, Solar Panels, Components / Devices, etc..
OptiOmega is a collection of products specialized for photonic integrated circuit simulation. It automates the design flow for
generating compact models from device level simulations. The software package includes two solvers that can be used via
Python scripting: Vector Finite Difference (VFD) Mode Solver and Finite Difference Time Domain (FDTD) Electromagnetic Solvers.

In this journal at Fig. 3 and at Fig. 4 Low Pass Bessel filter is used. I have seen similar simulation diagrams, where, after a photodetector a low pass filter is used to filter out the electrical signal.
But why is it necessary to use a low pass filter?
Why not other types of filters?
Can anyone explain?
Thanks in advance.
Dear ZH,
The filter after used after the pin detector is a lowpass filter because the pin detector is a square low device which makes the spectrum of the desired signal at baseband.
Regards,
Ahmad
