Abstract :
The spurious-free dynamic range of a sub-octave externally modulated optical analog link can be extended to as high as 138 dB-Hz with modest received optical power (only 2.3 mA average photocurrent!) and with very small noise figure penalty by using a simple linearized modulator design biased near its minimum transmission.<>
