    Abstract: A power sourcing equipment (PSE) device (110) of an optical power supply system (1A, 1, 1B) includes a semiconductor laser (111) that oscillates with electric power, thereby outputting feed light. The semiconductor laser includes a semiconductor region exhibiting a light-electricity conversion effect. A semiconductor material of the semiconductor region is a laser medium having a laser wavelength of 500 nm or less. A powered device (310) of the optical power supply system includes a photoelectric conversion element (311) that converts feed light into electric power. The photoelectric conversion element includes a semiconductor region exhibiting a light-electricity conversion effect. A semiconductor material of the semiconductor region is a laser medium having a laser wavelength of 500 nm or less.

    IPC: H04B10/80

    Abstract: A first optical communication device is provided with a laser light source 3 for emitting communication light CL and a transmitting optical fiber 11 arranged in water WA and having a light incident end portion 14 on which the communication light CL is incident. The transmitting optical fiber 11 transmits the communication light CL incident on the light incident end portion 14 toward the tip end portion 15. The transmitting optical fiber 11 is provided with a core part 21 configured to transmit the communication light CL from the light incident end portion 14 toward the tip end portion 15 and a clad part 23 covering the core part, the clad part being configured to emit at least a part of the communication light CL that transmits the core part 21 from a side surface of the transmitting optical fiber 11.
