Color free WDM PON based on broadband optical transmitters |
摘要 |
A Wavelength Division Multiplexed Passive Optical Network (WDM-PON) includes a plurality of broadband light sources, each broadband light source being connected to receive a respective data signal and generating a corresponding modulated broadband optical signal. An Array Waveguide Grating (AWG) is connected for receiving each modulated broadband optical signal through a respective branch port and for generating a filtered broadband signal. The AWG implements a filter function comprising a respective pass-band associated with each branch port such that the filtered broadband signal exhibits a respective intensity peak associated with each pass-band. Each intensity peak is modulated with data from a respective one of the broadband light sources. A bandwidth of the respective modulated broadband optical signal generated by each broadband light source is at least equal to the width of a channel-band of the AWG.
