Abstract
Chaotic message encoding and decoding in unidirectionally coupled
vertical-cavity surface-emitting lasers (VCSELs) with polarization-preserved
and polarization-selected optical injection has been studied experimentally.
A GHz message has been successfully encoded in the chaotic transmitter and
decoded from the receiver with polarization-preserved optical injection. In
contrast decoding using polarization-selected optical injection was achieved
at only 330 MHz. It has also been demonstrated that GHz message extraction
can be achieved using both normal and inverse chaos synchronization thus
providing an opportunity for exploiting polarization properties of VCSELs
for duplexed chaotic message transmission.
