We propose a system for the error-free changing of optical-access-line routes using delay lines with ringbuffer memories. The approach allows adjustment within 20km at a speed of about 487m/s with no impact on transmission quality.
This paper shows a modulation-format transparent optical-label switching transmitter based on optical arbitrary waveform generation. Every generated packet consists of a payload and a label; labels are extracted by a fiber Bragg grating.
40-bit OOK, 80-bit QPSK and 120-bit 16-QAM packets are generated with spectral efficiencies of 1, 2 and 3 b/s/Hz, exploiting concepts from OAWG. Results demonstrate potential for a Tb/s OAWG based transmitter using GHz electronics.
A novel WDM detection technique based on ultrafast field sampling is used to measure the chromatic dispersion of optical fibers. Its simultaneous two-wavelength detection enables direct evaluation of group delay difference without optical demultiplexing devices.
We demonstrate a modulation format transparent optical-arbitrary-waveform transmitter at 360 Gb/s including precompensation for dispersion. Proof-of-principle transmission of 9-bit OOK and DPSK signals across a 10-km SMF link are demonstrated with spectral efficiency of 0.53-b/s/Hz.
With a 16-arm AWG with amplitude and phase modulators on each arm we generate arbitrary filters and perform dispersion compensation of 2.5-ps pulses across 53 km of field fibre.
This paper demonstrates precise line-by-line optical pulse shaping using an arrayed-waveguide grating (AWG) pair and optical combs. Cross-correlation frequency-resolved-optical-gating characterized complex fields of arbitrary waveforms with phase errors less than ?? 0.02 rad.
