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:
“The character of the logger’s admiration is betrayed by his very mode of expressing it.... He admires the log, the carcass or corpse, more than the tree.... What right have you to celebrate the virtues of the man you murdered?”
—Henry David Thoreau (1817–1862)
“F.R. Leavis’s “eat up your broccoli” approach to fiction emphasises this junkfood/wholefood dichotomy. If reading a novel—for the eighteenth century reader, the most frivolous of diversions—did not, by the middle of the twentieth century, make you a better person in some way, then you might as well flush the offending volume down the toilet, which was by far the best place for the undigested excreta of dubious nourishment.”
—Angela Carter (1940–1992)
