SOLID-STATE TECHNIQUES FOR MODUALTION AND DEMODULATION OF OPTICAL WAVES.
Abstract
A number of new types of modulators were developed and tested to compare with the theoretically expected performance and to compare with KDP in its conventional longitudinal mode of operation. The results obtained are as follows: A hexamethylene-tetramine light modulator was constructed and sucessfully operated. A 45-degree Z-cut KDP crystal light modulator operating with a field transverse to the light path was constructed and sucessfully operated to several hundred megacycles. A KDP distributed line modulator employing four sections of KDP was constructed and found to operate to frequencies of several hundred megacycles. Using quartz at piezoelectric resonance (2.8 mc) a modulator was operated with near 100% modulation using less than a volt of driving power. A traveling wave quartz modulator was constructed with a 50-cm length. There was very little light loss and the device gave an order of magnitude more modulation than a single piece of longitudinal KDP under equal driving conditions. Deuterated KDP has been grown and is being prepared for testing. (Author)
