Optical sinc-shaped Nyquist pulses of exceptional quality

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

Sinc-shaped Nyquist pulses possess a rectangular spectrum, enabling data to be encoded in a minimum spectral bandwidth and satisfying by essence the Nyquist criterion of zero inter-symbol interference (ISI). This property makes them very attractive for com ...

Optical Nyquist-pulse generation with a power difference to the ideal sinc-shape sequence of < 1%

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Camille Sophie Brès, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

Sinc-shaped Nyquist-pulses possess a rectangular spectrum. Thus, a sinc-pulse transmission minimizes the carrier spacing down to the baud rate, and therefore, substantially increases the transmissible data rates. These perspectives have led to a strong res ...

Experimental investigation of pulse generation with one-pump fiber optical parametric amplification

Camille Sophie Brès, Mohammad Amin Shoaie

In a recent study, the theory of pulse generation with fiber optical parametric amplification using sinusoidal (clock) intensity modulated pump was revisited [1]. This work showed that the pulses generated through such parametric interaction exhibit a shap ...

Near-Nyquist optical pulse generation with fiber optical parametric amplification

Camille Sophie Brès, Mohammad Amin Shoaie

A novel method using optical fiber parametric amplification and phase modulation is proposed in order to generate Nyquist pulses. Using parabolic pulses as a pump, we show theoretically that it is possible to generate Nyquist pulses. Furthermore, we show t ...

Approximate Capacity of the Dirty Multiple-Access Channel With Partial State Information at the Encoders

I-Hsiang Wang

In this paper, we consider the K-user Gaussian multiple-access channel with multiple independent additive white Gaussian interferences. Each interference is known to exactly one transmitter non-causally. The capacity region is characterized to within a bou ...

Time/frequency coding for Brillouin distributed sensors

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

In this paper, we propose a novel coding for long range Brillouin Optical Time Analysis (BOTDA) distributed sensors based on a combination of time and frequency pulses, resulting in an additional coding gain of √2 with respect to traditional intensit ...
