We propose a simple and flexible spectral shaping technique based on nonlinear differential coding for short-reach IM-DD transmission. Experimental results show the achievement of 7% HD-FEC threshold in 186-Gb/s 10-km transmission with 14-GHz bandwidth limitation.

The dynamic strain sampling rate of Brillouin-based distributed sensors is limited by fiber length. For breaking this limit, a Brillouin optical time domain collider is proposed. A 10-times enhancement on sampling rate is experimentally demonstrated.
