“…2). Comparing two modulation formats with the same bandwidth, the difference in required OSNR can be given by determining P avg /D 2 min for both formats and calculating their ratio [3]. This is only valid for low error rates.…”

We present the design guidelines for novel passive ar-\ud rayed waveguide grating (AWG) devices to all-optically implement\ud time-frequency packing techniques in orthogonal frequency divi-\ud sion multiplexing (OFDM) systems. The proposed approach can\ud increase the spectral efficiency in long-haul fiber links. We analyze\ud the system performances, evaluating the maximum achievable in-\ud formation rate and spectral efficiency, and we found the optimal\ud AWG layout to maximize the overall system capacity. We demon-\ud strate, through simulations, that an overall 1.4 Tb/s transmission\ud over 200 GHz bandwidth can be reached, using two polarizations,\ud quadrature phase shift keying modulation, and digital feedback\ud equalization
