Everyone knows the well-known fact that the superposition of an LCP and RCP wave is simply linearly polarised light.
However, I am looking at the superposition of 2 RCP waves, where one is pi/2 out of phase with the other. Doing the Jones vector addition of these 2 gives a vector of
E = (1/sqrt(2))*(i+1;i-1)T
What is the physical meaning of such a superposed wave?
I'm sure that the previous reply is more than enough. Just let me add an intuitive point of view: adding CP waves is a process vervy similar to adding LP waves. Adding two RCP will give you another RCP in the same way that adding two parallel LP will give you another LP parallel to them. In both cases the phase between them will determine the amplitude of the resulting wave.
The key is that coefficient before the Jones matrix has no effect on polarization state. Detail answer can be found in upload file.
I hope my answer can help you.
interestingly it seems to me that because this is just phase offsetting that the wikipedia page on Phasors applies, looking at Mike's and Zhanchen's answers: https://en.wikipedia.org/wiki/Phasor
phasors seem to be kinda "out of fashion" if you know what i mean, because their use seems to be well-known in electronics, not mathematics and physics. i have been wondering if phasors could be used, and it looks like they can.
