Investigated were the opportunities of direct conversion of modulated laser radiation with mean power of 10–40 dBm for combined power and information transfer fiber-optic lines. Have been studied optical sensors based on common p-n AlGaAs/GaAs and n-p GaInP/GaAs structures, including the ones with multiple photovoltaic cells, providing acceptable efficiency values at optical-to-electrical conversion at wavelength 809–830 nm. Developed was a special circuit allowing extraction of the information signal at one time with power conversion. Shown, that at 30–35 dBm of incident power, laser power converters can demonstrate up to 55 % efficiency and 500 MHz bandwidth. Maximum laser source modulation depth in these modes shouldn’t exceed 3.5 %.
