ABSTRACT:
It includes: a substrate; a plurality of optical data processing units arranged in an array on the substrate, a super graphite sheet on LEDs of the optical processing units, and a glass substrate on the super graphite sheet. Each optical data processing unit includes an optical signal receiving circuit on the substrate for receiving an optical signal and generating a reception signal; a data processing circuit on the substrate for processing the reception signal and generating resultant data; a drive circuit and an LED on the substrate for emitting an output optical signal and heat in accordance with the resultant data. The super graphite sheet on the LED transmits and radiates the heat from the LEDs. The super graphite film is provided by sintering a high polymer sheet and has a high heat conductivity. The optical signal receiving circuit receives the optical signal through the glass substrate or through the substrate made of silicon of which thickness is reduced for providing transparency or in which a through hole is formed. An optical data processing system including a plurality of optical data processing apparatus are coupled directly or through a coupling optics or a coupling optical system.
