Abstract
A system for simultaneously transmitting multifrequency signals including a laser light source having a shared gain section and an addressable gain section. A first group of signals modulating the addressable gain section of the laser produces a plurality of wavelength division multiplexed channels. The second group of signals modulates the shared gain section of the laser such that each of the multiplexed channels is modulated with the signals from the second group.
