Direct detection with an optimal transfer function: toward the electrical spectral efficiency of coherent homodyne detection

Direct detection with an optimal transfer function: toward the electrical spectral efficiency of coherent homodyne detection

Complex-valued double-sideband direct detection (DD) can reconstruct the optical field and achieve a high electrical spectral efficiency (ESE) comparable to that of a coherent homodyne receiver, and DD does not require a costly local oscillator laser. However, a fundamental question remains if there...
