Abstract

An improved fiber optic tap monitor has characteristics that are flatter over the wavelength range of interest. The polarization dependence of the characteristics of the tap monitor is reduced, and the package for the tap monitor is smaller. The tap monitor reduces the amount of light reflected back to the source. The tap monitor is also assembled in a manner to improve temperature stability, so that its characteristics over a range of temperatures are more nearly constant.
