ABSTRACT:
A fiber optic communication system comprising:an optical signal source adapted to receive a binary base signal having a bit period T, and generate a first signal, wherein the first signal is frequency modulated; andan optical spectrum reshaper (OSR) adapted to reshape the first signal into a second signal, wherein the second signal is amplitude modulated and frequency modulated;characterized in that:the optical signal source is a laser in which frequency modulation is generated by modulating the loss of the laser cavity.A method for transmitting a signal, comprising:receiving a binary base signal having a bit period T, and generating a first signal, wherein the first signal is frequency modulated; andreshaping the first signal into a second signal, wherein the second signal is amplitude modulated and frequency modulated;characterized in that:the first signal is frequency modulated by using a laser in which frequency modulation is generated by modulating the loss of the laser cavity.A fiber optic communication system comprising:an optical signal source adapted to receive a binary base signal having a bit period T, and generate a first signal, wherein the first signal is frequency modulated; andan optical spectrum reshaper (OSR) adapted to reshape the first signal into a second signal, wherein the second signal is amplitude modulated and frequency modulated;characterized in that:the optical signal source is a laser in which frequency modulation is generated by modulating the phase of the laser cavity.
