Time Division Multiplexing of Interferometric Sensors at 1300nm Using a Litium Niobate Amplitude/Phase Modulator
A network of interferometric sensors for sensing discrete frequency components is processed using an integrated-optic amplitude and phase modulator to create both a phase carrier and the pulses for multiplexing using time division. A sampling technique employing computer control is used to account for optical cross-talk in time division processing due to the poor extinction ratio of the integrated optic device. A very high frequency phase carrier is also demonstrated using the same device.
