OPTICAL INTERFACE MODULE FOR COHERENT RECEPTION, OPTICAL MEMORY MODULE AND OPTICAL MEMORY SYSTEM INCLUDING THE SAME

摘要

An optical memory module includes: one or more memory devices storing data; and one or more optical interface modules mediating the optical communication between the memory devices and an external devices. The optical interface module includes: an input/output (I/O) light distribution unit which divides the received light to provide the transmission light and the reception light; an electrophotic conversion unit which performs a modulation operation based on the transmission light and an electrical transmission signal to generate an optical transmission signal; and a coherent photoelectric conversion unit which performs a coherent reception operation based on the reception light and an optical reception signal to generate an electrical reception signal.
