Design and characterization of a novel power over fiber system integrating a high power diode laser

Single-Fiber Combined Optical Power and Data Transmission for High-Voltage Applications

“…Recently, exceptional high power levels have been reported. A POF assembly with 30 W electrical power output using four OPCs with more than 10 W each has been demonstrated [30]. In [16], 20 W of electric power was extracted under 43 W of laser power, and in [31], the feed light has a maximum power of 60 W delivering over 7 W to a remote unit.…”

“…The reliability of the OPC used in the experiments for this article has been demonstrated in [14] and the reliability of fibers subjected to high-power laser pulses is investigated in [18]. In order to prolong system lifetime, a fiber break detection method with dual fiber cable is suggested [30]. Moreover, dispensed optical fibers have been developed to decrease coupling losses by direct contacting of opto-electronic devices [34].…”

“…One option is to add redundancy in all potential single points of failure. This approach has been applied for POF system in [30]. Another way is to implement a thermal management scheme to reduce the components' working temperature as well as the output power variance of the laser.…”

“…Another way is to implement a thermal management scheme to reduce the components' working temperature as well as the output power variance of the laser. Such power management schemes have been proposed in [26], [30], [35], [36]. Finally, condition and health monitoring measures can enhance the reliability of POF-based systems.…”

Quasistatic thermal and nonlinear processes of photoconversion of high-density optical radiation by multilayer structures

“…A typical example of such converters designed for flow densities over 10W/cm 2 is a layered silicon structure offered by MH GoPower [1,2]. Real operating conditions for such photo converters revealed a number of significant features and limitations, associated essentially with the thermal-and photoself-action of the converted flow at high radiation concentrations and insufficient heat removal from the site.…”
