Realization of a 23.9 Gb/s Real Time Optical-OFDM Transmitter with a 1024 Point IFFT
Realization Optical-OFDM Transmitter Point IFFT
2015/5/20
We report a FPGA-based real time 23.9-Gb/s CO-OFDM transmitter with IQ-mixing with a 1024 point FFT, the largest FFT-size reported to date. For a BER of 10 -3 a required OSNR of 10.8 dB is measured.
Experimental Realization of a Low-loss Nano-scale Si Hybrid Plasmonic Waveguide
Nano-scale Si Plasmonic Waveguide
2015/5/15
A novel hybrid plasmonic waveguide with nano-scale confinement, consisting of a metal layer separated from a SOI nano-rib by a thin silica layer has been realized. The loss of 0.01dB/μm allows for ult...
Realization of Optical OFDM Using Time Lenses and Its Comparison with Conventional OFDM for Fiber-optic Systems
Realization Conventional OFDM Fiber-optic Systems
2015/7/17
It is proposed to use Fourier transforms in optical domain using time lenses both at transmitter and at receiver to realize optical OFDM. Results show that coherent OFDM systems have higher nonlinear ...
