A versatile, wavelength-slicing device, referred to herein as an optical spectrum synthesizer (OSS), provides new avenues and technologies for optical communication applications. Specifically, OSS separates a composed optical signal into two output spectra. Each output spectrum carries a multiple of optical communication signal channels. The bandwidth of each channel and spacing between adjacent channels may differ from one output to the other. The cascades of OSS devices, the combinations of OSS with prior art components and modules, and other new devices to be used in conjunction with OSS lead to new Spectrum Devices that add new dimensions to existing and new optical network architectures. The invention of OSS leads to new Spectrum Wavelength Division Multiplexing and management devices based on cascades of OSS devices. Examples of these devices include Spectrum Multiplexer, Spectrum Demultiplexer and Spectrum Add Drop Module. The combinations of OSS and other prior art devices also lead to several new Spectrum devices and modules. Examples of these include, Spectrum Switch, Spectrum Cross-Connect and Spectrum Long Haul Transport Modules. Other devices designed to be used in conjunction with OSS, e.g., 1/n Multiplexer and 1/n Demultiplexer, can also be used to form new devices and modules.
