Optimized Optical Filtering For 40 Gb/s/Channel Optical Differential Quadrature Phase Shift Key (DQPSK), In DWDM Systems For Acces Network

The optimization of multiplexing (MUX) and demultiplexing (DMUX) 3-dB filter bandwidths for the optical differential quadrature phase shift key (DQPSK) combined with the return-to-zero (RZ) and carrier-suppressed returnto-zero (CS-RZ) is performed. The study of different optical signals in the 40 Gb/s dense wavelength division multiplexing (DWDM) system, with high spectral efficiency, is shown ...

Polarization-insensitive, 40 Gb/s wavelength and RZ-OOK-to-RZ-BPSK modulation format conversion by XPM in a highly nonlinear PCF.

Polarization-insensitive wavelength conversion, as well as the conversion of return-to-zero (RZ) ON-OFF keying (RZ-OOK) to RZ binary phase-shift keying (RZ-BPSK), has been simultaneously achieved at 40 Gb/s for the first time by cross-phase modulation (XPM) in a highly birefringent, nonlinear photonic crystal fiber (PCF). A 10-9-BER receiver sensitivity conversion penalty of < 3 dB was achieved...

Gb / s Optical Transceivers : Fundamentals and Emerging Technologies

Continued demand for higher bandwidth in data networks along with an industry need for standardized network components has driven the need for 10 Gb/s optical transceivers into the long haul, metro core, and enterprise/storage environments. In response to this demand, the functionality and performance of these modules have increased significantly, while the size, cost, and power consumption hav...

Wavelength multicasting in silicon photonic nanowires.

We demonstrate a scalable, energy-efficient, and pragmatic method for high-bandwidth wavelength multicasting using FWM in silicon photonic nanowires. We experimentally validate up to a sixteen-way multicast of 40-Gb/s NRZ data using spectral and temporal responses, and evaluate the resulting data integrity degradation using BER measurements and power penalty performance metrics. We further exam...
