ABSTRACT

Directional Coupler is one of the devices used in signal transmission techniques in optical fiber communication systems, especially Wavelength Division Multiplexing (WDM). The directional coupler can be used as a sensitive sensor, one of which is based on wavelength shifts and coupling length shift. This paper simulates a shift in wavelength and coupling length based on the influence of temperature in the range of 30℃ to 230℃ based on the characteristics of power output. The wavelength used in this simulation is in the C-Band region, which is around 1550 nm. Temperature changes cause changes in the material refractive index. Temperature changes cause a shift in wavelength and coupling length increase which describes the characteristics of the thermo-optic effects on the directional couplers.
