Scientists have developed new laser power converters that can transmit power to remote destinations. Developed by researchers at the University of Ottawa, the new approach can now help devices be connected and powered with a simple optical fiber over long distances, even in the. Photonic or laser power converters are crucial components in power-by-light systems. The current-feedback amplifier OPA623 provides additional gain in the AGC section and drives.
