Intrinsic losses in photovoltaic laser power converters

Applied Physics Letters, 2021
Using photovoltaic cells as photovoltaic laser power converters (PLPCs) is a potential technology for long-range wireless power transfer. Intrinsic processes that limit the performance of PLPCs have not been fully investigated. Based on a thermodynamic model, we categorize and calculate the intrinsic losses in PLPCs.

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 ...

GaAs converter for high power laser diode

Conference Record of the Twenty Fifth IEEE Photovoltaic Specialists Conference - 1996, 1996
Transmission of electrical power in an optical form is of increasing interest. Many applications of this technique can have high conversion efficiency over 50%. An optical power transmission system consists of a laser (acting as a power source) and a photovoltaic device, eventually coupled by an optical fiber used as a waveguide.

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,

High power laser diode driver based on power converter technology

IEEE Transactions on Power Electronics, 1997
This paper describes the design of a high speed semiconductor laser diode driver designed for driving 500 mW to 1.5 W diodes at full optical power modulation up to frequencies of 10 MHz. The duty cycle of the modulation may be varied. A switching power-converter based current source allows a higher power delivery efficiency to the diode than in ...
