Abstract

In this paper the possibility of optical pulses spectral measurement using optical fiber as a dispersive system is examined. We study obtaining sample spectra which are new to optical range. Single pulse passage through a dispersive system with linear group delay frequency dependence is the basis of studying a spectral device based on optical fiber. This analysis is performed using optical radiation complex spectrum definition. Complex sample spectrum in optical range can be obtained by using a dispersive system. Examination the single optical pulse distribution in a dispersive medium is the theoretical basis of measurement the complex sample spectrum. Dispersive system is considered to be an optical four-pole network. The dispersive system parameters are defined to allow the optical signals complex spectrum measurement. Known photo detectors of optical range produce electrical signals as electrical field intensity square. According to this, power characteristics of analyzed optical signal and spectral measurement results ratio is introduced. Photo detection produces a sample power spectra sequence. We examine the possibility of power spectrum assessment algorithm proposed by Jenkins and Watts utilization. This method is based on sample power spectra summation. Qualities of acquired power spectrum assessment are examined.
