WDM transmission in 1.0.MU.m band over PCF using supercontinuum source

Abstract

Abstract:We achieved the first wavelength division multiplexed (WDM) transmission in the 1.0 μm band over a 6 km PCF. As a light source, we generated a supercontinuum (SC) with a −10 dB bandwidth of 2.8 THz in a 1 km-long, low loss PCF. Four 10 Gb/s WDM signals obtained from part of the SC with arrayed waveguide gratings (AWG) were successfully transmitted with negligible power penalties. We show the possibility of realizing WDM transmissions at more than 1 Tb/s in the 1.0 μm band over a low loss PCF by using a supercontinuum source.

Absorption Change Induced by Electric Field of an InGaAsP/InAlAs/InP Asymmetric Quantum Well Structure Gown on InP Substrates

“…Figure 3 shows the absorption spectrum of the asymmetric MQW sample at room temperature. It is known from this figure that the absorption edge is located at around 1.06 m. This wavelength is suitable for ytterbium-doped fiber amplifiers (YDFAs) for the optical fiber communication in the 1-m-wavelength region [6][7][8] and for YAG lasers, which are widely used in various fields. 9,10) In order to confirm the absorption change induced by the applied bias direction, the applied bias dependence of the photo-current spectrum was measured.…”
