WAVELENGTH DIVISION MULTIPLEXED OPTICAL MODULATOR

摘要

A method and apparatus for automatically providing for both multiplexing and independent external modulation of two or more wavelengths emitted by a multi-longitudinal mode laser. The present invention uses an integrated optics device chip to enable coupling of the dispersed wavelengths into separate electro-optic modulators which encode each of the carrier wavelengths with a different signal. Accordingly, the volume of data which can be transmitted over an optical fiber network is increased.
