Thanks a lot for you and for the others reply. I will check the link you provided.

Thank you for your concern. Actually, I mean the photodetector. We can assume it as 100% efficiency, where each photon will emit electron and for each electron there is a response function h(t) contains charge q.

Thank you for the reply. My question is about Photodetector with impulse response h(t). Where the output current is represented by i(t) = sum{ h(t-tm) } where h(t) is the response of one electron such that int{h(t)}=q and tm is the time of released electron.

Hi, I am a little bit confused about the impulse response of one electron. Assume that we have LTI system characterized by impulse response h(t) with unit gain, int{h(t)} = 1. Let the input is current i(t) [Amp]. So the output current will be i(t)*h(t). We can view it as i(t) is...

Hello, Let's try to simplify the problem... Assume we have linear polarization in x-direction i.e. E = \cos(\omega t - \beta z) \hat{x} or we can write it as E = cos(\beta z - \omega t) \hat{x} . This wave is a traveling wave.. means that it moves in the direction of \hat{z} ...
