- Abstract :
We experimentally demonstrate four-channel multiplexing of
64-bit (8~8) two-dimensional (2-D) parallel data links on the basis
of optical space-code-division multiple access (CDMA) by using new
modules of optical spatial encoders and a decoder with a new
high-contrast 9-m-long image fiber with 3~104 cores.
Each 8~8 bit plane (64-bit parallel data) is optically encoded
with an 8~8. 2-D optical orthogonal signature pattern.
The encoded bit planes are spatially multiplexed and transmitted
through an image fiber. A receiver can recover the intended input
bit plane by means of an optical decoding process.
This result should encourage the application of optical space-CDMA to
future high-throughput 2-D parallel data links connecting massively
parallel processors.
