“…To the best of our knowledge, 125Gbaud is the highest baud rate record for the all-optical Nyquist QPSK signal generation, and coherent detection by one receiver based on digital signal processing. The previous record baud rate for one coherent receiver for full-band signal detection is 107Gbaud in4243 and 110GBaud in44.…”

Spectrum efficient data transmission is of key interest for high capacity optical communication systems considering the limited available bandwidth. Transmission of the high speed signal with higher-order modulation formats within the Nyquist bandwidth using coherent detection brings attractive performance advantages. However, high speed Nyquist signal generation with high order modulation formats is challenging. Electrical Nyquist pulse generation is restricted by the limited sampling rate and processor capacities of digital-to-analog convertor devices, while the optical Nyquist signals can provide a much higher symbol rate using time domain multiplexing method. However, most optical Nyquist signals are based on direct detection with simple modulation formats. Here we report the first experimental demonstration of high speed all optical Nyquist signal generation based on Sinc-shaped pulse generation and time-division multiplexing with high level modulation format and full-band coherent detection. Our experiments demonstrate a highly flexible and compatible all optical high speed Nyquist signal generation and detection scheme for future fiber communication systems.

In parallel a 1.15-Tbit/s (5×230-Gbit/s) quasi-Nyquist spaced wavelength division multiplexing (WDM) superchannel transmission over the same 820 km optical field link (FL) was also investigated through numerical simulations based on the same 57.5-Gbaud DP-QPSK signal using 1% roll-off Nyquist pulse shaping with 60-GHz channel spacing, and the results indicate that the BER performance well below the 7% overhead hard-decision FEC error-free threshold (4.5×10 -3 ) for the 1.15-Tbit/s DP-QPSK superchannel transmission can be achieved.

“…In order to enhance the data-carrying capacity of single mode fiber (SMF), researchers have explored multiplexing techniques in time, wavelength, and polarization comprehensively [1]- [3]. Recently, the prospect of capacity crunch in SMF has stimulated widespread interests in mode division multiplexing (MDM) using few-mode fiber (FMF), together with multi-input multi-output (MIMO) signal processing technique [4]- [8].…”

We propose and experimentally demonstrate a robust mode converter based on liquid crystal-on-silicon (LCOS), which is not placed at the focal plane of the collimating lens. We present theoretical investigations to evaluate the performance of proposed configuration, and our experimental results verify the favorable function of mode-selective conversion with orthogonal linear polarizations, as well as two-mode multiplexing. The robust device configuration with an insertion loss of less than 3 dB, together with cascade capability, can be used for multidimensional fiber-optical transmission system. In particular, in terms of LP 11 mode conversion, the off-focus operation allows the range of position offset for input fiber with graded-index (GRIN) lens, LCOS, and few-mode fiber to be 7.5 mm, 151 m, and 40.4 mm, respectively, indicating easy alignment and maintenance.
