Abstract

Optical device technologies for photonic networks, are focusing on integrated optical device technologies for digital coherent optical transmission technologies. With the rapid spread of fiber to the home (FTTH), broadband video services and mobile Internet devices now require a highly functional optical network infrastructure with a large capacity 100-Gbit/s/channel system based on digital coherent technology is considered to be a promising candidate for next-generation large-capacity long-distance optical communication systems. The optical components required for such systems, such as Polarization Division Multiplexed Quadrate Phase Shift Keying (PDM-QPSK) optical modulator, integrated receiver, and local light source, are under development. Opto-electrical integration technologies, which enable us to construct small, low-cost, and highly functional optical components, will play an important role in providing cost-effective transmission equipment for future 100-Gbit/s/ch and post-100-Gbit/s/ch optical communications.
