N2 - We present a simple approach based on photonic reservoir computing (P-RC) for modulation format identification (MFI) in optical fiber communications. Here an optically injected semiconductor laser with self-delay feedback is trained with the representative features from the asynchronous amplitude histograms of modulation signals. Numerical simulations are conducted for three widely used modulation formats (onx2013;off keying, differential phase-shift keying, and quadrature amplitude modulation) for various transmission situations where the optical signal-to-noise ratio varies from 12 to 26x00A0;dB, the chromatic dispersion varies from x2212;500 to 500x00A0;ps/nm, and the differential group delay varies from 0 to 20x00A0;ps. Under these situations, final simulation results demonstrate that this technique can efficiently identify all those modulation formats with an accuracy of gt;95RC layer such as the injection strength, feedback strength, bias current, and frequency detuning. The proposed technique utilizes very simple devices and thus offers a resource-efficient alternative approach to MFI.
