Which lab is this?..Very interesting video thread
Which lab is this?..Very interesting video thread
Experimental demonstrations in earlier videos are from the fiber optics laboratory of Prof. Xiaoyi Bao at the University of Ottawa in Canada, where I wrote my PhD thesis. Less glamorously, the videos on numerical simulation are recorded in my apartment.
@@yourfavouriteta When I was a student of fiber optics course, I had few questions. One of those is, If I illuminate a non-PM fiber by a source which is unpolarized, what will be the polarization state of the output beam? Will it be unpolarized or elliptically polarized?
I have some other questions also, I would like to know from you if you allow😊😊
@@jackoflove4307 If the incident light is unpolarized, the light exiting the fiber (whether it's PM or non-PM) will also be unpolarized.
As a side note, there is, in some sense, no such thing as "unpolarized light". Imagine placing an ultra narrow filter in front of an incoherent light source, such as an incandescent light bulb. Imagine also, that you use a "magical" polarimeter with an extremely high sampling rate to measure the polarization of the filtered light over time. You will find that the measured state of polarization changes extremely quickly, but that it has a definite, measurable SOP at any given instant. As long as you can sample more quickly than the light can alter its SOP, it will appear polarized. If the sampling rate is lowered to the point where the light transitions between multiple different SOPs during the collection of a sample, only the "average" polarization in that interval can be reported.
Please let me know if you have any other questions.
@@yourfavouriteta Why the excited modes like LP01 is called linearly polarized, it has no connection with the SOP of the light?!
