Paper Abstract

NTT Electronics Corporation (NEL) provides active and passive photonic devices for WDM fiber optics networks and is contributing to the development and enhancement of optical communication systems. Active devices include uncooled DFBs that can be directly modulated at 10Gb/s up to 85C, 10 Gb/s EA-DFBs with EA driver, 10Gb/s photodiode module with pre-amplifier and limiting amplifier. Passive devices are PLC (Planar Lightwave Circuit)-based deices such as AWGs (Arrayed Waveguide Gratings) for wavelength MUX and DEMUX, for example, ultra-low loss AWGs with insertion loss of as low as 2 dB and optical matrix switches. The performance of these devices are discussed.
