Abstract
A single channel 100 Gb/s dual-polarization quadrature phase shift keying transmission based on injection-locked broadband quantum-dash Fabry-Perot laser, and employing external modulation, has been demonstrated. By employing a far L-band similar to 1621-nm sub-carrier, -17.4-dBm sensitivity at the bit error rate 3.8x10(-3) has been obtained after 10 km standard single mode fiber transmission. Besides, an injection locked mode wavelength tunability of similar to 23 nm, which translates to similar to 50 subcarriers, is accomplished. These results favor the viability of deploying broadband quantum-dash lasers as unified upstream and downstream transmitters in next generation wavelength division multiplexed-based passive optical networks.
