Ultrahigh capacity optical transmitter with dispersion precompensation.

摘要

The continuing growth in Internet traffic demands a scalable backbone Internet infrastructure. In particular, optical transmitters must continually be upgraded in order to support next generation bandwidth demands. The creation of a next generation optical transmitter requires overcoming obstacles such as chromatic dispersion and the limited speed of the driving electronics. As a result, the continual need for increased Internet bandwidth demands a new optical transmitter methodology to achieve the ultrahigh data rates necessary to maintain rapid growth.;Proof-of-principle experiments indicate that optical arbitrary waveform generation (OAWG) based data modulation is a viable means of transmitting ultrahigh data rate signals. Experimental results provide verification of a modulation format transparent, high-capacity communications transmitter based on OAWG (OAWG transmitter) at 360 Gb/s, including precompensation for chromatic dispersion. Demonstrations of a proof-of-principle transmission of 9-bit on-off keying (00K) and differential phase-shift keying (DPSK) signals across a 10-km single-mode fiber (SMF) link yield a spectral efficiency of 0.53-b/s/Hz. Theoretically, compensation of an arbitrary amount of chromatic dispersion is possible using an OAWG transmitter.
