Demonstration of a prototype bandwidth-on-demand broadband access network using monolithically integrated coherent transceivers

Summary form only given. Among the few potential broadband access schemes, the coherent dense WDM technology is advantageous to provide a system with very small channel spacing, easy channel selection, and massive-user support due to its superior receiving sensitivity and electronic tuning and filtering capability. The authors report the demonstration of a prototype access network with multiple wavelength channels and users using tunable coherent transceivers operating under a counter-receiving heterodyne detection system.
