Abstract: Provided herein are a multi-channel receiver optical sub-assembly and a manufacturing method thereof. The multi-channel receiver optical sub-assembly includes a PLC chip having a first side into which an optical signal is received and a second side from which the received signal is outputted, with an inclined surface formed on the second side of the PLC chip at a preset angle, a PD carrier bonded onto the PLC chip and made of a glass material, and an SI-PD bonded onto the PD carrier, a lens being integrated therein. The PLC chip, the PD carrier, and the SI-PD are passively aligned by at least one alignment mark and then are bonded.

Abstract: A multiple output quantum random number generator coherently measures an optical source noise and outputs a random number sequence based on the independent and coherent measurement of optical source noise. Therefore, it is possible to output a random number sequence at a high speed and to perform multiple outputs.

Abstract: There is provided a receiver optical module including a photodetector having a plurality of channels, a capacitor disposing block formed on an upper portion of the photodetector, a plurality of capacitors formed on the capacitor disposing block, and an electrical wiring configured to connect the plurality of capacitors to electrodes of a plurality of channels of the photodetector, wherein the plurality of capacitors are formed on the capacitor disposing block such that distance between the capacitors and the electrodes of the corresponding channels are the same. Distortion and loss of signal characteristics of high frequency can be reduced and quality of a signal can be enhanced.
