Abstract: Embodiments disclose a server system including a first circuit board which includes a first socket connected to a memory controller via an electrical channel; and a second circuit board which is combined with the first socket such that signals are exchanged with the memory controller via at least one of the electrical channel and an optical channel. The optical channel is combined with the electrical channel via an electrical-to-optical conversion device, the electrical-to-optical conversion device converts an electrical signal into an optical signal or converts an optical signal into an electrical signal.

Abstract: An optical transmitter includes photonic integrated circuits configured to respectively output optical transmission signals in different wavelength ranges. A photonic integrated circuit may include emitters configured to emit beams having different wavelengths; drivers configured to respectively provide power to the emitters, and a wavelength division multiplexer configured to transmit the beams emitted by the emitters. A photonic integrated circuit may include a switch device that controls the drivers, and light detectors configured to detect intensities of the beams emitted from the emitters. The switch device may selectively operate at least one driver of the plurality of drivers based on information associated with intensities of the beams. The switch device may selectively operate a driver connected to an emitter, based on a determination that an intensity of a beam emitted by another emitter is less than a threshold intensity value.
