| Zusammenfassung: | A wavelength division multiplex integrated optical transmitter and optical transmission system employing narrow band filters to dramatically improve tolerance to chromatic dispersion and thereby enable increased reach and/or data rates and a method of offering a communication service using such a transmitter or system. The transmitter comprises an array of semi-conductor lasers 21-24, and an arrayed waveguide grating (AWG) 25-28 which acts both as a wavelength selective combiner and as the narrow band filters. Each filter has its centre wavelength offset from the centre wavelength of the respective laser. |
