Abstract :
We achieved successful low-input-power (-10 dBm) wavelength conversion at 10 Gb/s by using a hybrid integrated cross-phase modulation wavelength converter (XPM-WC). The input CW power was also -10 dBm and the total current was only 215 mA, and no signal preamplifiers were used. From the relationship between the eye-opening ratio and the injection current to the SOA, we clarified the optimal current condition for low-input-power operation. The XPM-WC consists of a two-channel spot-size converter integrated semiconductor optical amplifier (SS-SOA), which is mounted on a planar lightwave circuit (PLC) platform. We also fabricated an 8-slot unit. XPM-WC modules are inserted in every slot and can operate independently. Stable and uniform low-input-power operation is confirmed in all slots.
