1.3-цm waveband 10-Gbaud quadrature-phase-shift-keying signal transmission over 4-km holey fiber using quantum dot laser

A 1.3-μm waveband 10-Gbaud photonic transport system transmitting quadrature-phase-shift-keying (QPSK) signals over a 4-km single-mode holey fiber was demonstrated using a newly developed wavelength-tunable quantum dot (QD) laser fabricated through the sandwiched sub-nano separator technique.
