Successful lasing of buried heterostructure GaInAsP SCH MQW laser diode on silicon substrate has been achieved. BH laser structure was obtained by wet etching and a few steps MOVPE regrowth using directly bonded InP/Si substrate.

We experimentally demonstrate the transmission of a net rate of 250 Gb/s/lambda using PAM-6 and PAM-8 IMDD over 1-km single-mode fiber using commercially available components. A power sensitivity of -6dBm (-5dBm) is achievable for PAM-6 (PAM-8).

We propose a compact angle-of-arrival (AoA) tracking system without requiring the beacon light. The proofof-concept experimental demonstration shows that the proposed system improves the tolerance to AoA fluctuations by ~3 times.

A novel routing, core and spectrum assignment (RCSA) algorithm based on reinforcement learning is proposed for space division multiplexing elastic optical networks (SDM-EONs). The algorithm introduces two metrics that measure the spare capacity of the network in terms of the inter-core crosstalk in multi-core fibers and the efficiency of spectrum resource utilization. Numerical simulations indicate that it can enhance the network capacity by up to 46.8% and 10.4%, compared with two conventional schemes.
