We present a bandwidth scalable optical transmitter for creating high bandwidth optical signals using parallel low speed electronics. Proof-of-concept 20 GHz spectral width, 100 ns, 10 Gb/s DPSK and 20 Gb/s QPSK waveforms are generated.
This letter demonstrates the efficacy of an optical arbitrary waveform generation (OAWG) transmitter in generating high-bandwidth, single-channel optical waveforms with precompensation overcoming chromatic dispersion. Specifically, 20-bit, 200-Gb/s differential phase-shift keying and 40-bit, 400-Gb/s quadrature phase-shift keying packets are precompensated for the 1675.16 ps/nm of dispersion and 4...
This paper presents single channel, 200 Gb/s, 20-bit DPSK packets generated by an optical arbitrary waveform generation based optical transmitter with chromatic dispersion precompensation, and their transmission through 100 km of single-mode-fiber and recovery.
We demonstrate a security enhancement mechanism based on four-state temporal optical coding which protects a SPECTS O-CDMA upstream link against eavesdropping including DPSK detection. The FPGA-based code-hopping implementation facilitates future encryption by optical codes.
