Phase operator in quantum optics

    I recently got interested in some aspects of quantum optics and have a basic question.

    There is an uncertainty relation concerning the phase and the particle number of a mode. How is this phase observable defined?

    Where can I read about such basic concepts without dwelling deeply into higher order correlation functions and the like?

    Prof. Balakrishnan gives a great lecture on the quantization of free EM radiation in a cube. In the end of the lecture, he discusses one simple possibility way define the phase operator and shows that it leads to serious problems:

    All lectures on QT should be like that - interesting, careful, pointing out also deficiencies of the theory.

    I have found that there is also this review:

    Thanks Jano, I am going to watch this. And wow to this review book, 500 pages about the phase operator alone. ;-)

    I completely agree.
