Abstract
The feasibility of an all-optical fiber optic interface for sensors and
actuators is demonstrated. The interface module converts optical power
to electrical power for the use of the sensor or the actuator. In
addition, the module provides bidirectional optical data transmission
between the sensor or actuator and a control unit by using the
powerfeeding fiber as a data transmission media. Optical power and data
is transmitted to the sensor or actuator via a single multimode fiber.
The system comprises of a customized 10-cell photovoltaic array
illuminated by the use of a customized 1 x 10 integrated optics coupler.
A 41% optical-to-electrical power conversion efficiency was obtained
for the photovoltaic array, and a 27% total optical-to-electrical power
conversion efficiency was attained for the system. When a single element
in the array was biased as an LED, a -33 dBm optical power was coupled
to the multimode fiber.
