Patent ID: 7373044

Claim:
A signal transfer method in an information processor including at least a central processing unit, a memory and an input/output unit, the method comprising the steps of: providing electrical signals based on instructions of the central processing unit; generating a plurality of optical signals, in an optical signal generation unit, from the electrical signals; transmitting the optical signals, which are generated by the optical signal generation unit, inside optical waveguides via light receiving parts; and inputting instructions from the central processing unit into other devices by receiving the optical signals emitted from the optical waveguides and converting the optical signals into electrical signals, wherein the step of generating optical signals includes the steps of generating optical signals by driving surface emitting elements in response to the electrical signals, deflecting a direction of the light beams transmission by use of an optical bend including aspherical lenses formed in accordance with the optical signals and coupling the deflected light beams with a plurality of optical waveguides via the aspherical lenses formed in accordance with the light beams.
