Abstract
A sensing system tethered to an optical fiber for delivering optical power. A sensing system has a semiconductor device that includes photodiodes and a laser. The optical signal delivered through the optical fiber generates a current in the photodiodes that can be used to at least recharge the sensing system's power supply or bias the laser. The optical signal can be modulated to deliver data to the sensing system. The laser can be modulated to transmit data from the sensing system over the optical fiber. Because the power source can be recharged, the sensing system can also transmit and receive using an RF module.
