Description
Summary:Injection locked quantum-dash laser diode-based comb source is employed in wavelength-division multiplexed (WDM) optical transmission covering &#x223C;1610&#x00A0;nm L-band optical telecommunication window. An aggregate data rate of 192&#x00A0;Gbits&#x002F;s (3&#x00A0;&#x00D7;&#x00A0;32 GBaud-QPSK reaching 7&#x0025; FEC overhead) is demonstrated over three 50&#x00A0;GHz separated channels in coherent transmission over a 10 km-long single mode fiber. A thorough investigation of the radio-frequency (RF) characteristics of all channels is carried out in terms of the linewidth, phase, and frequency noises, showing minimum values of 44&#x00A0;kHz, &#x2212;80&#x00A0;dBc&#x002F;Hz, and 5.2&#x00A0;&#x00D7;&#x00A0;10<sup>11</sup> Hz<sup>2</sup>&#x002F;Hz, respectively. Also, an integrated average relative intensity noise of &#x223C;&#x2212;132&#x00A0;dB&#x002F;Hz is reported for the central channel. To the best of our knowledge, this constitutes the first report and demonstration of a dense WDM (DWDM) in an extended L-band regime using a comb source.
