We demonstrate 10Gbit/s transmission over a 5km photonic crystal fiber (PCF) in the 1.1µm band using a directly-modulated single-mode vertical cavity surface emitting laser (VCSEL).A combination of PCF and VCSEL enables us to achieve high-speed transmission at a low cost and with a simple configuration that does not employ optical modulators or amplifiers. Furthermore, the transmission distance was extended to 14km by using an ytterbium-doped fiber amplifier (YDFA), and a power penalty-free transmission was successfully achieved.
