Abstract :
An optical network device that is formed by three cascaded directional couplers is discussed in this paper. Wavelengths of 1535.04 nm, 1545.32 nm, 1555.75 nm and 1565.50 nm from ITU channels are the input signal sources that are used to study propagation in the designed device. The output results of these wavelengths through this optical network device are analyzed with the help of a BPM CAD simulator. The results of the analysis include insertion loss, crosstalk and bandwidth. For real device design and fabrication, the bending loss of this introduced optical network device is also discussed
