Description

This invited talk will review the development of ultrafast all-optical LAN technologies, conducted by New Energy and Industrial Technology Development Organization (NEDO), Japan. First, we will provide an outlook for the energy issues of future network equipment, then point out the importance of optical circuit-switched networks, particularly for the future local area networks in the forthcoming ultra-high definition, or 'Super Hi-vision', video era. To realize ultrafast all-optical LAN, we argue that scalable network interface card technologies are the key. As specific development topics, 40G-CMOS based optical transceivers, picosecond all-optical switching using the inter-subband transition (ISBT) devices, high-operating-temperature semiconductor optical amplifiers (SOA), and integrated wide-dynamic-range wavelength converters will be introduced.
