High-Efficiency Photovoltaic Power Converters and Application to Optical Power Transmission

2021 26th Microoptics Conference (MOC), 2021
Optical Power Converters (OPCs) based on Broadcom's multi-junction photovoltaic design enable high-efficiency optical-to-electrical conversion for applications at various wavelengths and output powers. This paper reviews how the output powers have been extended from < 1W to tens of Watts, and how the spectral range options cover the 800-830nm range, as

High-power optical parametric frequency converters with addressable wavelengths in the infrared

Proceedings of SPIE, 2017
Based on established short pulse lasers with an output wavelength around 1 μm optical parametric frequency converters open up the spectral range between 1.4 and 4.0 μm for the first time in a power range of interest to laser material processing. The systems can be flexibly adapted as regards wavelength, pulse parameters and spectral properties to the ...

Fiber Optic Power Converter

SPIE Proceedings, 1989
Fiber optic sensor and communication technology has developed a need for generating electric power at remote locations where conventional methods cannot be used. A fiber optic monolithic array of optical power converter cells was developed to meet this need. Optical power and information can be transported over optical fiber at different wavelengths. A

Laser Power Converters for optical power supply

Proceedings of the 2011 34th International Spring Seminar on Electronics Technology (ISSE), 2011
Laser Power Converters are dedicated semiconductor devices that convert optical energy into electrical energy. Opposed to solar cells they are optimised for high energy density and conversion efficiency mostly under laser illumination. These cells are applied as power supply in electromagnetically sensitive areas or for galvanic decoupling of ...
