Optical fibers only work because of total internal reflection. Fresnel’s Equations in optics R = 100% Laser medium R = 90% 0% reflection! 0% reflection! Many lasers use Brewster’s angle components to avoid reflective losses: Webθt = °. Fresnel's equations give the reflection coefficients: = and. =. The transmission coefficients are. = and. =. Note that these coefficients are fractional amplitudes, and must be squared to get fractional intensities for reflection and transmission. The signs of the coefficients depend on the original choices of field directions. hawaii early learning profile curriculum
