Claim 15:
16. A method of enabling dispersion compensation on an integrated receiver chip configured for direct detection, the integrated receiver chip having a first and a second single polarization waveguide photodetectors, the method comprising steps of integrating a first and a second dispersion compensators on the integrated receiver chip, the first and the second dispersion compensators being optically connected to the first and the second single polarization waveguide photodetectors, respectively, the first and second single polarization waveguide photodetectors being electrically connected in parallel, such that photocurrents electrically transmitted from the first and the second single polarization waveguide photodetectors are combined, and providing a digital signal processor (DSP) in electrical communication with the first and the second dispersion compensators, the DSP being programmed to:
set initial dispersion compensator parameters;
enter scan operation mode;
scan through preset dispersion compensator parameters;
set the parameters for the best BER;
end scan operation mode;
enter tracking operation mode;
tune dispersion compensator parameters; and
find optimum BER.
