TL;DR: An optical fast Fourier transform scheme is demonstrated that provides the necessary computing power to encode lower-bitrate tributaries into 10.8 and 26.0 Tbit s-1 line-rate orthogonal frequency division multiplexing (OFDM) data streams and to decode them from fibre-transmitted OFDM data streams.

TL;DR: The analogy to optical orthogonal frequency division multiplexing is discussed and it is shown that using appropriate algorithms, Nyquist pulse shaped modulation formats can be encoded on a single wavelength at speeds beyond 100 Gbit/s in real-time.

TL;DR: In this paper, a remotely seeded flexible passive optical network (PON) with multiple low-speed subscribers but only a single optical line terminal transceiver operating at a data rate of 31.25 Gbps/s is demonstrated.

TL;DR: A new modulation scheme with a sensitivity of 2.3 photons per bit at a bit-error ratio (BER) of 10(-3) is discussed theoretically and demonstrated experimentally.

TL;DR: In this paper, an ultra-dense network architecture designed for silicon photonics at the optical network unit (ONU) is introduced, which allows up to 12 Gbit/s of symmetric traffic in a single 12.5GHz optical channel.
