Photovoltaic element, Laser Power Converter
A photovoltaic element (Laser Power Converter, LPC) is a device that receives laser light from a remote location via fiber and converts that laser light into electrical power. There are versions designed for short wavelengths based on 850 nanometers GaAs and for long wavelengths based on 1400 nanometers InGaAs. They are used differently for short-distance and long-distance transmission. A few years ago, when we received a request from a customer, this product did not exist in the market. We developed it in collaboration with a technology group in the United States. The initial specifications required a clean power supply for sensors and amplifiers needed for various measurements in environments with poor noise conditions. Metal transmission was not feasible. Fiber power supply made it possible. Now, it has become an essential component for low-noise amplifiers in remote antennas for terrestrial digital broadcasting. Its use is also expected in remote antennas for mobile phones that require high-speed, high-capacity communication. It is becoming an essential part for specifications that require noise-free power supplies in locations where metal cannot provide power. The supply voltage can be accommodated from 2V. The conversion efficiency of laser light to power is currently achieving 35%.
