Chiral Metamaterial Produces Record Optical Shift Under Incremental Power Modulation
Chiral Metamaterial Produces Record Optical Shift Under Incremental Power Modulation
2017/3/14
Georgia Institute of Technology researchers have demonstrated an optical metamaterial whose chiroptical properties in the nonlinear regime produce a significant spectral shift with power levels in the...
Record Low Loss, Record High FOM Optical Fiber with Manufacturable Process
Record Low Loss Record High Optical Fiber Manufacturable Process
2014/11/6
Record-low loss of 0.149dB/km at 1550nm is realized by pure-silica-core fiber having optimally enlarged Aeff, which indicates record-high figure-of-merit for digital coherent system.Mass-productivity ...
Record Switching Throughput of 1.28-Tbit/s/port (64-wavelength x 20-Gbit/s) by DWDM / NRZ-DQPSK Optical Packet Switch System
DWDM / NRZ-DQPSK Optical Packet Switch System
2015/7/20
We first achieved error-free (BER<10 -9 ) operation of 1.28-Tbit/s/port (64-wavelengths x 20 Gbit/s)DWDM/NRZ-DQPSK optical packet switching and buffering, and demonstrated throughput-scalability could...
Single-Mode Holey Fibers with Record Aeff of 50,000μm
Single-Mode Holey Fibers Record Aeff
2015/7/16
We demonstrated a single-mode holey fiber (HF) with record Aeff of 50,000 μ m 2 at 1.0 μ m. Fabrication trials to realize Aeff of 80,000 μ m 2 were also performed and novel potentials could be confirm...

Strictly single-mode fibres with record core-diameters of 82 m@1 m and 130 m@1.55 m are demonstrated.They have parabolic index profile with record low index differe...
Record 505 km Unrepeatered 4x43Gb/s APol-RZ-DPSK Transmission
Unrepeatered APol-RZ-DPSK Transmission
2015/7/30
The Alternate Polarisation-RZ-DPSK modulation format extends the 43 Gb/s unrepeatered transmission distance to 505 km, with E-PSCF fibre, third-order Raman pumping and a remotely-pumped amplifier.
