  • Ensuring of reliability of discrete information reception in coherent FOTSI [fiber optic transmission systems] 
    NISTIRIUK, P. V.; TSURKAN, D. N.; BEREGOI, E. A.; ALEXEI, A. S.; BIRZOI, O. S.; KORNEA, C. I. (IEEE, 2002)
    Described in this paper are different reception homodyne schemes for coherent FOTSI interference immunity increase. Coherent FOTSI immunity depends on the optical oscillator shot noise and laser phase noise, stipulated by ...
  • Far-field and near-field methods for optic fiber characterization 
    BORSCIOV, V. I. (Institutul de Fizică Aplicată, AŞM, 2018)
    Optical fibers play an important role in modern technologies. They are largely used both in industrial and civil applications: telecommunications, defense and aerospace, test and measurement, automotive, chemical, and ...
  • Fluorescence properties of As2S3 glass doped with rare-earth elements 
    IOVU, M.; ANDRIESH, A.; CULEAC, I. (National Institute of Optoelectronics, Romania, 2005)
    Chalcogenide glasses doped with various rare-earth ions are extensively studied as potential materials for fiber optic amplifiers operating at 1.3 and 1.5 µm telecommunication windows. The experimental results on optical ...
  • IR sensing by fiber-optic speckle based interferometer 
    CULEAC, I. P.; NISTOR, Iu. H.; ANDRIESH, A. M.; IOVU, M. S.; ZAGONENCO, V. F. (Institutul de Fizică Aplicată al AŞM, 2012)
    In the previous papers we presented a speckle-based fiber optic method for registration of low intensity infrared radiation, which is based on the interference of propagation modes in the far field of a multimode fiber. ...
  • Raman Spectra in As-Based Chalcogenide Optical Fibers 
    IOVU, M. S.; CULEAC, I. P.; KOUDELKA, Ladislav; VOYNAROVYCH, Ivan; VLCEK, Miroslav (American Scientific Publishers, 2014)
    Raman spectra for optical fiber samples prepared from As-based chalcogenide glass composition (As50S50, As40S60, As25S75, (As40S60)0.95:(As40Se60)0.05 and (As40S60)0.95:(Sb40S60)0.05 are investigated. The primary maximum ...
