All-optical OFDM demultiplexing by spectral magnification and band-pass filtering.

چکیده
We propose a simple OFDM receiver allowing for the use of standard WDM receivers to receive spectrally advanced OFDM signals. We propose to spectrally magnify the optical-OFDM super-channels using a spectral telescope consisting of two time-lenses, which enables reduced inter-carrier-interference in subcarrier detection by simple band-pass filtering. A demonstration on an emulated 100 Gbit/s DPSK optical-OFDM channel shows improved sensitivities after 4-times spectral magnification.

TuB 4 80 to 10 Gbitls Demultiplexing using Fiber Cross - Phase Modulation and Optical Filtering
Future ultra high bit-rate optical time division multiplexed (OTDM) systems may require all-optical demultiplexing to down convert high bit-rate data to e.g. 10 Gbit/s or 40 Gbit/s where electronic circuits can be used. Many suggestions of such demultiplexers have been proposed over the years. The most common device is the nonlinear optical loop mirror (NOLM) that allows switching due to cross ...
متن کاملA Novel Transmitter Architecture for Spectrally-Precoded OFDM
Frequency nulling spectral precoding is an approach that suppresses the out-of-band emission in OFDM systems. In this paper, we discuss the transmitter architecture of the spectrally precoded OFDM systems. We design a novel precoder that matches the practical implementation of the OFDM modulator. We show that spectral precoding can relax the analog low pass filtering requirements of the OFDM sy...

متن کاملClassification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...
متن کاملDesign of fiber-integrated tunable thermo-optic C-band filter based on coated silicon slab
Background: Optical filters are required to have narrow band-pass filtering in the spectral C-band for applications such as signal tracking, sub-band filtering or noise suppression. These requirements lead to a variety of filters that offer thermo-optic effect for optical switching, however, some of which without proper thermal and optical efficiency. Methods: In this paper we propose a tunable...
