“…However, to be suitable for advanced communication schemes, these circuits must be able to handle hybrid MDM/WDM transmissions. For example, some integrated mode couplers compatible with WDM transmission have been recently proposed [12,13] as well as integrated WDM filters operating on different modes simultaneously [14]. In this Letter, we propose and experimentally demonstrate for the first time, to our knowledge, a photonic integrated cir-cuit for shortreach few-mode-fiber transmission performing simultaneous mode and wavelength demultiplexing.…”

A photonic integrated circuit performing simultaneous mode and wavelength demultiplexing for few-mode-fiber transmission is demonstrated for the first time. The circuit is realized on an InP-based technological platform; it can handle up to eight mode- and wavelength-division-multiplexed (MDM/WDM) channels and allows all-optical multiple-input-multiple-output processing to unscramble mode mixing generated by fiber propagation. A single arrayed waveguide grating is used to demultiplex the WDM channels carried by all the propagating modes, optimizing circuit complexity, chip area, and operational stability. Combined with an integrated wideband mode multiplexer the circuit is successfully exploited for the transmission of 10 Gbit/s on-off-keying non-return-to-zero channels with a residual cross talk of about -15 dB.
