Paper Abstract

We successfully demonstrate 10-Gbbaud quadrature phase-shift keying signal transmission over a 4-km-long endlessly single-mode holey fiber using a wavelength-tunable semiconductor quantum dot (QD) laser. The transmission is carried out in the waveband of 1040.72–1070.02 nm with a bandwidth of 7.89 THz, which is broader than conventional wavebands such as the C and L bands. In the study, a QD laser notable for its wavelength stability and tunability is employed for its broad bandwidth availability on the transmission. Observed bit error rates are within a forward error correction limit of 2×10–3 under homodyne coherent detection configuration with offline digital signal processing. The abundant frequency resources in this T band (1000–1260 nm) help increase the capacity of a transmission link using a large number of wavelength channels by the QD laser.
