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 17

Large mode area single-mode fibers usually have a rather small numerical aperture,

(a) because this is required for achieving single-mode guidance

(b) because this helps to limit bend losses

(c) because this makes it possible to attenuate higher-order modes via bending

(d) because that makes them compatible with standard single-mode fibers
