Efficiency limits of laser power converters for optical power transfer applications

Journal of Physics D: Applied Physics, 2013
We have developed III-V-based high-efficiency laser power converters (LPCs), optimized specifically for converting monochromatic laser radiation at the eye-safe wavelength of 1.55 m into electrical power. The applications of these photovoltaic cells include high-efficiency space-based and terrestrial laser power transfer and subsequent conversion to ...

Photovoltaic laser power converters for wireless optical power supply of sensor systems

2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2016
Optical power transmission (also called power-by-light) is an elegant solution to power wireless sensor nodes. At the sensor, optical power in form of monochromatic laser light is converted to electricity by photovoltaic laser power converters. These photovoltaic cells are optimized for the monochromatic wavelength of the light — opposed to solar cells,

Analysis of Probe Signal Power Dependence of All-Optical Wavelength Converter Using Semiconductor Optical Amplifiers

Japanese Journal of Applied Physics, 2001
We analyzed the influence of the probe signal power on the wavelength conversion in an interferometric all optical wavelength converter using semiconductor optical amplifiers (SOAs). The carrier density variation inside an SOA due to longitudinal signal amplification and nonradiative recombination is investigated and the following variation of ...

Low input power wavelength converter using a gain-clamped semiconductor optical amplifier

The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003
A laser wavelength converter using a gain clamped (GC) SOA was proposed for low input power characteristic. Wavelength conversion from communication wavelengths of 1530 to 1560 nm to fixed wavelength of 1510.8 nm was experimentally demonstrated for CW and data at 2.5 Gb/s input signals.
