Dense Wavelength Division Multiplexing Technologies for Local Access Networks

摘要

Objective: Develop a low-cost, monolithic dense WDM technology for multi-Gb/s LANs consisting of multi-wavelength VCSEL arrays (1x16) with local wavelength regulation, and an add-drop multiplexer technology for wavelength selection. Approaches and Goals: * develop a quasi-planar single-growth technique for achieving multiwavelength VCSEL and REPD arrays * demonstrate local wavelength tuning to regulate the wavelengths of individual VCSELs * demonstrate multi-channel WDM transmission at >2.5 Gb/s/channel * achieve a 16 channel WDM VCSEL array with a channel spacing of approx. 2-3 nanometers (40 Gb/s aggregate throughput) * monolithic ADM technology for wavelength selection.
