160-Gb/s optical-time-division multiplexing with PPLN hybrid integrated planar lightwave circuit

Abstract
160-Gb/s (20 Gb/s /spl times/ 8) optical time-division-multiplexing is demonstrated using a multiplexer based on periodically poled lithium niobate hybrid integrated planar lightwave circuits. With this multiplexer, eight 20-Gb/s signals are independently modulated and time division multiplexed all-optically. To confirm the quality of the multiplexed signal, it was demultiplexed and bit error rates were measured. The measured power penalties are less than 2.2 dB.
