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 14

Two multimode fibers with different core sizes but same numerical aperture are spliced together. Light is sent into the fiber with the smaller core. How about the splice loss?

(a) The losses at the splice can be substantial, since the mode fields do not fit.

(b) There cannot be significant splice losses, since all light gets into the core of the second fiber.
