Abstract

An optically powered device using an InGaAs photodiode has been developed. This study aims to harvest light energy (2.8 to 500 μW) from the FTTH (fiber-to-the-Home) network and to utilize it for operating remote sensors without an external energy source. We designed the booster circuit and evaluated its characteristics, confirming that it could boost an input voltage of 0.3 V to 3.0 V. We also evaluated the characteristics of an InGaAs photodiode and confirmed that it could output a voltage over 0.3 V using 10-μW input light. We demonstrate that a ready-made sensor can be operated with an input optical power as low as 10 μW.
