Abstract :
We demonstrate a 1.55-μm wavelength 5-GHz analog heterodyne optical link employing an integrated balanced photodiode (BPD) with a noise figure of (20/spl plusmn/1) dB and spurious-free dynamic range of (102/spl plusmn/2) dB/spl middot/Hz23/. A wide-band rectifier narrow-band receiver architecture is employed to allow for phase noise cancellation. The advantage of BPD over a single photodiode is also explored.
