| 英文摘要 | An apparatus and method provides optical multiple wavelength signals using a single, broadband optical source 18 such, for example, as an LED, to generate many independent optical wavelength channels. An optical transmitter includes a wavelength channel defining assembly 22 which resolves the broad spectrum pulses output by the source into discrete wavelength bands constituting respective pulses (i.e., wavelength channels) and which inserts a delay between the bands to define a sequence of individually addressable channels. In accordance with one embodiment of the invention, spectral splicing is achieved by a waveguide grating router 36, and insertion of the respective delays is achieved by individual fiber sections 38, each section having a length selected to introduce a particular delay, coupled to the output ports of the router. The inserted delays can be conveniently selected to separate adjacent wavelength channels and thereby minimize the likelihood of crosstalk. Pulses of the thus-resolved channels arrive at different times to a multiplexer 40 which may be configured, for example, as a passive WDM multiplexer or as a star combiner. The resulting sequence of addressable wavelength channels may be supplied to one or more high-speed, broadband modulators 26, with each modulator being operable to modulate some or all of the channels. |
