研究目的
To present the experimental implementation of an all-optical ROADM scheme for routing of an individual subchannel within an all-optical OFDM superchannel.
研究成果
The scheme demonstrated operates for both single and dual quadrature formats, and clearly scales to multi-terabit/s superchannels through the use of additional sub-channels, and opens the way for guardband-free all-optical ?exible transport.
研究不足
The experimental node demonstration was based on optical fibre and discrete devices in a research laboratory environment, where the optimum interference condition may only be achieved for short period of time. A second stabilization circuit was implemented to mitigate the thermally and mechanically induced phase difference between the two arm of the long extract interferometer.
