The Photonics Quiz

Test yourself by solving a set of questions concerning laser technology, optical fibers, and nonlinear optics! The following questions are mostly solvable by using the RP Photonics Encyclopedia. Note that in some cases more than one answer is correct.

Question 26

Is the following statement true: What happens in a degenerate optical parametric oscillator (OPO) is exactly the time-reversed version of resonant frequency doubling.

(a) Yes, why not?

(b) No, these processes rely on different nonlinearities.

(c) No, these processes differ in terms of phase matching.

(d) No, as a time-reversed frequency doubler would have two input waves, whereas the OPO has only one.
