WDM (wavelength division multiplexing) is a powerful technique available to meet
the ever-increasing demand for communication bandwidth. Among the WDM
techniques, the grating is widely used. Fiber gratings selectively reflect a narrow range
of wavelengths; this becomes important in designing demultiplexers.
This paper presents a design idea to build a WDM demultiplexer component using
Fiber Bragg Grating (FBG). The results obtained reveal that the suggested design is
powerful in achieving accurate demultiplexer design. We aim to demonstrate the high
level accuracy, the time and cost saving from using the latest state of art software. The
performance was measured using quality factor (Q. Factor) and bit error rate (BER),
available via visualizers Component Library, included in Optisystem simulator.
