Optics is the study of light, and its interaction with matter. It includes topics such as imaging systems, fiber optics, lasers, quantum optics, and more.

Diffraction limited divergence angle
Divergence $\theta=0$ is not possible -- from a quantum mechanical perspective, it would violate the Heisenberg uncertainty principle for position and momentum of a photon. "Collimated" is not really …

Functions of the Glan-Taylor beam splitter cube
Yes, the light would still be polarized. The second half makes the output beam direction less sensitive to the input angle, and makes the polarizer symmetric so it can be used in reverse as well.
Yes …

What is an intuitive explanation of Gouy phase?
Feng and Winful's paper (cited above by Igor Ivanov) gives a good explanation.
A plane wave is defined by a single wavevector $\mathbf{k}$, so its wavefronts are equally spaced. The plane waves compo …

Model for fibers optics
You just need to calculate the maximum incidence angle for total internal reflection (for larger angles, the refracted ray will leak out of the fiber). Since angle of incidence equals angle of reflect …

When plane waves interfere, is the resulting wave also a type of plane wave?
The question you're asking seems to be about reflection, not interference. The reflection is not necessarily a plane wave.
If the reflecting object has a curved surface, the wavefronts will be distor …
