Opt Express 18:21376-85. 2010..5 Gbps, POL-MUX 256 ( = 16X16)-ary OCDM transmission using a single multi-port optical encoder/decoder (E/D). We show that this architecture reduces the number of required optical codes and enhances the system confidentiality...
- Noise suppression using optimum filtering of OCs generated by a multiport encoder/decoderTakahiro Kodama
Department of Electrical Electronic, and Information Engineering, Osaka University, 565 0871 Osaka, Japan
Opt Express 20:10320-9. 2012..We numerically and experimentally demonstrate an enhancement of the code detectability, that allows us to increase the number of users in a passive optical network (PON) from 4 to 8 without any forward error correction (FEC)...
