Exact modeling of photonic crystal fibers for determination of fundamental properties
Autor: Suslov D.; Komanec M.; Němeček T.; Bohata J.; Zvánovec S.
(ELSEVIER SCIENCE INC, 2020)We present a simple but highly accurate modeling technique for real photonic crystal fibers (PCFs) characterization. We determine the influence caused by idealized model parameters. Our technique can be applied to arbitrary ... -
Experimental all-optical relay-assisted FSO link with regeneration and forward scheme for ultra-short pulse transmission
Autor: Nor N.A.M.; Komanec M.; Bohata J.; Ghassemlooy Z.; Bhatnagar M.R.; Zvánovec S.
(Optical Society of America, 2019)This paper presents experimental results for an all-optical free-space optical (FSO) relay-assisted system by employing an all-optical regenerate and forward (AORF) scheme in order to increase the transmission link span. ... -
