The spectral reconstruction of Fourier transform spectrometer can be simply achieved by using
a Fourier transform or a Fourier cosine transform. However, the traditional Fourier transform
solution i...
Novel Optical Fast Fourier Transform Scheme Enabling Real-Time OFDM Processing at 392 Gbit/s and Beyond
Optical communications Discrete optical signal processing
2015/6/10
An optical FFT scheme is implemented and tested at 392 Gbit/s. It enables OFDM sig-nal processing way beyond the bandwidth limits of electronics. The scheme operates with little energy as it exploits ...

Four-wave mixing Nonlinear optical spectroscopy Fourier-transform spectroscopy
2009/6/2
We propose nonlinear Fourier-transform spectroscopy using a broadband pulse, which can discriminate the origin in Four-wave mixing (FWM) process. By taking account of the response function of a sample...
Holographic optical elements for Fourier transform (HOE-FT) used in the optical memory system are considered in this paper. The determination of the optimal page composer capacity allows for the appro...
