Abstract:
An analog optical system for transmitting an analog optical signal on an optical channel, said optical signal having a bandwidth greater than 1 GHz, said system comprising:a transmitter for transmitting the optical signal, said transmitter including an optical modulator responsive to a carrier signal and an RF input signal, said modulator modulating the carrier signal with the RF signal to generate the transmitted optical signal, said modulator supporting the bandwidth of the optical signal and having high-fidelity, wherein the modulator includes an optical waveguide and opposing electrodes, where the opposing electrodes having a length such that the modulator operates as a frequency modulator for an RF signal having a first frequency and as a phase modulator for an RF signal having a second frequency, the second frequency being higher than the first frequency; and a receiver receiving the optical signal from the optical channel, said receiver including an optical demodulator, said demodulator demodulating the optical signal to remove the RF signal from the carrier signal said demodulator supporting the bandwidth of the optical signal and having high-fidelity.
