Résumé :

Abstract This article presents a way of analyzing the transfer function of electronic signal amplifiers. It also describes the possibility of using signal precorrection which improves the parasitic harmonics in the THD (Total Harmonic Distortion) of the amplified signal by correcting linearity of the tested amplifier’s transfer function. The proposed method of analyzing and presenting the transfer function allows to diagnose the causes of generating parasitic harmonics, what makes it a useful tool when designing low distortion amplifier systems, such as e.g. amplifiers in measurement systems.

Résumé :

Abstract In this paper, the effects of pump pulse fluence on the output energy and amplified spontaneous emission (ASE) of a femtosecond regenerative amplifier are investigated. One can easily enhance the output energy of laser amplifiers by increasing their pump fluence. This in turn can increase the ASE and reduce the performance of amplifiers in terms of output beam quality, beam stability, etc. This effect would eventually lead to what is called ‘temporal intensity contrast deterioration’. In this work, it is shown that an optimum state of the pump pulse fluence can indeed optimize the amo

Résumé :

Modern wireless communication systems use spectrally efficient modulation schemes to reach high data rate transmission. These schemes are generally involved with signals with high peak-to-average power ratio (PAPR). Moreover, the development of next generation wireless communication systems requires the power amplifiers to operate over a wide frequency band or multiple frequency bands to support different applications. These wide-band and multi-band solutions will lead to reductions in both the size and cost of the whole system. This dissertation presents several advanced power amplifier solut

A number of techniques have been implemented to demonstrate an exceptionally wide and flat FOPA gain of 10.5±0.5 dB over 102 nm bandwidth on a single side of the FOPA pump. A flat gain spectrum is targeted here because FOPA is prone to large gain variation which has a particularly strong negative impact o

We demonstrate experimentally and by computer simulation that the semiconductor optical amplifiers (SOAs) are capable of performing a variety of optoelectronic (OE) functions useful in fiber-optic networks and optical signal processors at multi-Gb/s rates[1,2]. An example of OE functions obtained is a complete optical regeneration of data pulses which are amplified, retimed, and reshaped in optical domain. In this paper, we present results on a 1.55 μm traveling-wave (TW) SOA optical regenerator with a novel clock recovery circuit for retiming and synchronization. The regenerator operates at a
