Y. Suzuki et al., OPTICAL-DEVICES FOR OPTICAL ACCESS NETWORKS - RECENT PROGRESS IN SEMICONDUCTOR OPTICAL-DEVICES AND OPTICAL MODULES, Optical and quantum electronics, 30(3), 1998, pp. 141-159
Cost-effectiveness is essential in developing optical access network s
ystems. To reduce system costs, both improved system and component tec
hnologies are required. Reducing the costs of optical devices and modu
les in an optical network unit is especially necessary. in this paper,
the requirements for optical devices in optical access networks and m
odules are clarified. Moreover, we also review the recent progress in
technologies for semiconductor optical devices and hybrid integration
for low-cost optical modules in access networks.
