Student Samar Karim Ibrahim earned a master's degree from the Department of Laser Optical Electronics Engineering in the University of Technology the letter tagged: (based variable spectral filter using fiber Barak incised).
The Committee comprised discussion of Prof. Dr. Ali Yusuf Fattah, of the University of Technology as a president ,L. Shatha Mazhar Hassan of the Iraqi Commission for Computers and Prof. Dr. Jassim Kadhem Hamoud members ,Prof. Dr. Iyad Muhammad Zwain ,L. Abdullah Khudair Abbas supervisors ,all are from the University of technology.
And reached the researcher to study and analyze the performance of fiber Barak incised as a variable spectral filter using two different techniques are tensile techniques / compression and technique of temperature (heating) after it has been verified from the results of the theoretical analysis of both technologies and approved scientifically there are two vision packages have been verified their two traditional package (package C ) and long-package (package L) so as to cover the gain bandwidth pumps optical fiber hybrid between pumps arebeom vestiges pumps Raman
