Abstract
The development of an analog optical link capable of transmitting measured currents and voltages from anechoic chambers to remote control and data acquisition systems is proposed. The system is based on integrated optical modulator (IOM) coupled to a cw 1.3 mm diode laser and to a high frequency PIN diode photodetector. The main advantage of the external modulation of a laser light, is that modulating frequencies as high as 15 GHz can be very attractive for the proposed application. Recent advantaces in the fabrication of these modulators, based on an Annealed Proton Exchange process, have produced IOMs that are extremely stable for high optical power of a few hundred of milliwatts. A prototype unit will be developed and fully tested under the Phase I effort to demonstrate the functional capabilities of the proposed concept.
