Abstract

We demonstrated multiwavelengths formation by utilising a combination of fibre ring laser, three fbgs and 20 m of photonic crystal fibre (PCF) with zero dispersion wavelength at 1040 nm. Although it characteristics efficiently interacts in 1040nm range lasers in efficiency of non linear effects, we determined to exploit four wave mixing (FWM) effect in generating multiwavelength at C band transmission window. Prior, the Erbium Doped Fiber Amplifier (EDFA) spectrum was performed in order to identify its performance and suitable FBG. Two FBGs at the end of C band amplification and one fibre Bragg grating (FBG) at gain spectrum are selected. The FBGs assigned are FBG 1, 2 and 3 with its own specifications (1530.47 nm and reflectivity 89.9%), (1561.42 nm and reflectivity 91.6%) and (1563.95 nm and reflectivity 96.7%) respectively. Through FWM effect, new wavelengths generated successfully at gain spectrum range 1530nm to 1540nm. These findings show, multiwavelengths able to be generated even though the separation between signals which are not consistent at lengths and far among each other able to induce by sufficient energy level. The findings give a valuable impact and prospective relevance towards sensors and optical communications.
