Paper Abstract

Guidedwave optical modulators have been designed and tested for applications as electro-optic data link for electromagnetic sensing. The ruggedized data link consists of an injection laser diode pigtailed to a stress induced birefringent fiber, an electro-optic coupled channel waveguide modulator, a graded index multimode fiber for return signal, and a laser driver optical receiver electronics box. The electronics box can be physically separated from the laser diode-fiber-modulator-fiber assembly for ease in field installation. This link has demonstrated a frequency range between 10 kHz to 200 MHz, and a dynamic range of 40 dB at 200 MHz bandwidth operation.
