In fiber optics, mode volume is the number of bound modes that an optical fiber is capable of supporting.
The mode volume M is approximately given by and, respectively for step-index and power-law index profile fibers, where g is the profile parameter, and V is the normalized frequency, which must be greater than 5 for this approximation to be valid.
Famous quotes containing the words mode and/or volume:
“There are a thousand hacking at the branches of evil to one who is striking at the root, and it may be that he who bestows the largest amount of time and money on the needy is doing the most by his mode of life to produce that misery which he strives in vain to relieve.”
—Henry David Thoreau (18171862)
“The other 1000 are principally the old Yankee stock, who have lost the town, politically, to the Portuguese; who deplore the influx of the off-Cape furriners; and to whom a volume of genealogy is a piece of escape literature.”
—For the State of Massachusetts, U.S. public relief program (1935-1943)
