Hello Alidthu
Thank you for your suggestion,I will keep this in consideration from very next time.For now the basic idea is for sharing these papers is, the successive work of a particular author step by step from beginning to final proposal.So that it is easy to understand the real concept and application of wavelength conversion to enhance the system security.I coudnt get time today for forum replies,i am attaching a file here to get multiple wavelengths from one laser source by using EAM .
