Abstract :
An optical travelling-wave amplifier (TWA) is used as a combined mixer and preamplifier for 1.3 μm wavelength subcarrier-modulated optical signals. By modulating the TWA gain at the local oscillator frequency flo, sum and difference frequencies (f s±flo) are generated, where fs is the frequency of intensity modulation of the input signal
