Abstract :
A novel bit-by-bit code hopping scheme using single phase modulator is proposed and demonstrated for secure optical communication application. In the experiment, 2.5 Gbit/s DPSK data has been generated and securely transmitted over 34 km by scrambling five 8-chip, 20 Gchip/s Gold codes with prime-hop patterns.
