Wavelength selective photonic integrated switches for ROADM node functionality in ultrahigh capacity metro network

摘要

Photonic integrated wavelength selective switches are integral part of Reconfigurable add/drop multiplexer nodes and enable efficient utilization of resources in high-capacity metro networks. Photonic integrated wavelength selective switches play instrumental role in enabling dynamic reconfigurability and support efficient utilization of network resources. In this paper, design, and implementation of modular photonic integrated wavelength selective switches across integration platforms is presented. The modularity feature of the photonic integrated circuits (PIC) supports scalability for meeting the capacity requirement of the network. An experimental demonstration on a proof-of-concept SiPh/InP hybrid integrated wavelength selective switches is given. Results further verify the prospect of modular PIC implementation of WSS in fulfilling the dynamic re-configurability demand of high-capacity metro network.
