Abstract

One new wavelength-time code family with short code lengths is proposed for optical code-division multiple access networks. With the special structure of the proposed codes, economical optical components can be used for coder realization and the resulting tunable coders are simpler with fast tuning speeds. The performance analysis is taken the beat noise during the photo-detecting process into account, and it shows that these code words can obtain bit error rates comparable to that of previous codes with short code lengths.
