To obtain the degree of Doctorate in Optoelectronic Materials and Energy Design of communication systems based on broadbandsources for fiber and free space optical links

A WDM-OOFDM access network using a centralized optical transceiver based on a single optical broadband sliced source at the Central Office is presented as a low cost solution. Such network offers downlink and uplink signal transmission by using double sideband modulation and optical carrier re-use, as well as dynamic bandwidth allocation, multiple band selection and tunable OFDM band selection in reconfigurable networks at moderate bitrates.
