ABSTRACT:
A burst optical receiver includes an optical signal inlet, an optical-electrical signal converter, an AC coupling network, an integrator feedback network, and an electrical signal outlet. The AC coupling network is electrically communicated with the optical-electrical signal converter, and blocks the electric signal having the frequency ranges lower than a predetermined threshold frequency, and allows the electric signal having the frequency ranges above the threshold frequency to pass through. The integrator feedback network is electrically communicated with the AC coupling network, and recurrently modifies the electric signal from the AC coupling network in such a manner to minimize noise mixed with the electric signal such that the electric signal is sufficiently contrasted with the noise for maximizing a signal-to-noise ratio of the electric signal.
