AI Article Synopsis
- The study introduces a method to counteract inter-core skew in multi-core fiber links by adjusting the wavelengths of transmitted spatial channels.
- This technique was successfully tested with a high-speed spatial super channel consisting of four channels at 27.8 Gb/s over a 10.1 km length of 19-core multi-core fiber.
- The results indicate that inter-core skew can be compensated effectively without requiring additional devices like variable optical delay lines or electronic buffers.
Article Abstract
This work proposes an approach for the compensation of inter-core skew in homogeneous single-mode multi-core fiber links. We adjust the wavelengths of the transmitted spatial channels in such a way that the skew induced by group velocity counters inter-core skew. This approach is demonstrated experimentally using a 111 Gb/s spatial super channel (4 spatial channels at 27.8 Gb/s) on a 10.1 km 19-core multi-core fiber. It is shown that inter-core skew may be compensated without the need for devices such as variable optical delay lines or electronic buffers.
