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 28

Assume that a periodic picosecond pulse train is generated with a gain-switched laser diode. Does the spectrum of the pulse train have the shape of a frequency comb, consisting of sharp lines?

(a) Yes, it does, because periodic pulse trains always have such a spectrum.

(b) No, it doesn't, because the pulses are not mutually coherent.

(c) This depends on the quality of the electronic driver of the laser diode.
