We report single-channel 40-Gb/s signal transmission over nonzero dispersion-shifted fiber using an integrated electroabsorption-modulated laser in the transmitter for data modulation. Return-to-zero format pseudolinear transmission over 1200 km is achieved with a measured of 15.6 dB or bit-error rate of 10-9.

摘要

We demonstrate two 160-Gb/s modulation formats that posses the same intensity pulse profile but differ regarding their phase coding. We analyze the nonlinear transmission properties of both coherent modulation formats by experimental and analytical investigations. The results show that the pairwise alternating phase coded carrier suppressed return-to-zero (PAP-CSRZ) signal outperforms the nventional CSRZ format. Our modulation technique is even applicable at higher speed as demonstrated with the generation of the first CSRZ signal at a record rate of 320 Gb/s.

【期刊论文】Wavelength Blocking Filter With Flexible Data Rates and Channel Spacing

摘要

This paper presents a high-resolution (13.2 GHz) channel-blocking optical filter, suitable for use as a reconfigurable optical add/drop multiplexer (ROADM), which seamlessly supports data rates from 2.5 to 160 Gb/s. The filter consists of a linear array of 64 MEMS micromirrors and a high-dispersion echelle grating. The demonstrated device had an insertion loss of 9 dB, a loss ripple of 1.2 dB, and a group delay ripple of 15 ps. Data transmission through the device with various mixed data rate scenarios ranging from 2.5 to 160 Gb/s showed negligible penalty, except at 40 Gb/s where a maximum penalty of 1.5 dB was observed due to a phase coherence with the blocker filter ripple.

摘要

We report a simple and effective method to reduce the switching time of a semiconductor tunable laser.We perform simulation and experiment to investigate the limitation in achieving fast switching. A low output-impedance driver is used to effectively reduce the settling time of the diode current of the laser tuning section.
