Comprehensive analyses based on the rigorous vector diffraction theory were used to simulate the polarized readout signals using a solid immersion lens (SIL) in reading phase change (PC) disks. For an...
An optimized pulse shape is shown to reduce intra-channel nonlinear effects in a 10 Gbaud dual-polarization 16-QAM EDFA-amplified system without optical dispersion compensation.
Real-time detection of a 40 Gbit/s polarization-multiplexed square 16-QAM signal is demonstrated in an FPGA-based intradyne coherent receiver processing 100% of data. A minimum BER of 3.3×10 -5 is ach...
We demonstrate application of polarization-switched-QPSK subcarrier modulation together with soft-FEC LDPC coding and iterative demapping on OFDM lab system. 4.5dB OSNR-sensitivity improvement versus ...
By employing co-polarization dual-pump scheme, polarization insensitive and subchannel-preserved wavelength conversion of 432-Gb/s, dual-peak polarization-multiplexed O-OFDM QPSK signals has been real...
Parametric amplification of 112-Gbit/s-33%-RZ-DQPSK signals with 20 dB on-off- gain is shown using highly nonlinear fiber in a polarization diversity configuration. The measured OSNR penalty at a BER ...
Digital Subcarrier Multiplexing (DSM) allows simple direct detection of spectrally effi-cient multicarrier signals. We show through simulations that, by using DSM, the quality of DWDM transmission wit...
An all-optical polarization temporal signal processor is demonstrated, which performs well in 40-Gbits/s optical signal differentiation with error of ~0.1 and efficiency of ~12%, 80-GHz 3.3-ps optical...
We introduce digital lightpath labeling for DP-QPSK transmission, using novel binary encoding to embed a polarization-shift-keyed subchannel. An integrated inline polarimeter powers a compact label re...
An integrated coherent receiver module based on monolithically integrated 90° hybrids and balanced waveguide pin-photodiodes is presented. Optical transmission performance is demonstrated for a 224 Gb...
Output polarization is controlled by injecting current along crystalline directions. VCSELs with record-low threshold current of 0.19 mA and extinction ratio >21dB from fit is achieved. Polarization s...
New impairments in polarization-multiplexed ultrahigh-speed transmission in the presence of PMD and PDL are identified analytically and experimentally. Crosstalk is inevitable even with PSP launching,...
We evaluate PDL-induced penalties in PDM-QPSK coherent systems with both lumped model and distributed model. We find the lumped model significantly over-estimates PDL penalties and PDM coherent system...
For the first time, we demonstrate colorless 44-Gb/s/ upstream OFDMA-PON transmission with polarization-insensitive, source-free ONUs. Superior performance is reported over 20 km SSMF plus 1:3...
We demonstrate 160-Gb/s PDM 16-QAM single channel transmission over the longest distance yet to be reported, of 3123.9 km. The coherent receiver employs a frequency offset compensator based on a digit...
