We present preliminary data on the fidelity of an analog optical data link operating at 830 nm. This data link encodes an electrical signal on an optical carrier by the action of a commercially available integrated-optic modulator, a 2x2 switch, from Crystal Technology, Inc. (CTI). An optical streak camera is used to record the modulated optical carrier. With this single-shot system a precision of 2--5% is realized. The dynamic range of the system is approximately 30 dB (power). The present system bandwidth is limited to 3 Ghz by the CTI modulator. New modulator designs using travelling wave structures will soon extend the system bandwidth to around 10 Ghz. We discuss the potential for development of a high-fidelity multichannel analog link based upon this technology and the potential impact on instrumentation for the measurement of ultra-fast single-transient phenomena. 5 refs., 10 figs.
