Advanced optical communication systems and devices

This paper shows recent developments and achievements at Centro de Pesquisa e Desenvolvimento em Telecomunicações (CPqD), Campinas, Brazil, concerning advanced photonic devices based respectively on Silicon Photonics (SiP) and Thin Film Polymer on Silicon (TFPS™) integration technologies to drive the next generation of ultra-fast optical communication networks. The Brazilian's first SiP-based 100G DP-QSPK modulator and a 100Gbps DP-QPSK Transmit Optical Sub-Assemblies (TOSA) module, suitable for CFP2 transceivers are reviewed. CPqD extensive research and development programme, the largest of its kind in Latin America, has produced ICT solutions for both private and public corporations in communications, multimedia, financial, utilities, industrial, defence and security sectors. Its Optical System Division is in charge of numerous projects in high capacity / ultra-fast optical systems and networks management, (software-defined networking and smart algorithms) as needed for the forthcoming future high-capacity elastic optical networks.
