Numerical Analysis of Thermal Dependence of the Spectral Response of Polymer Optical Fiber Bragg Gratings
The thermal dependence of the spectral response (i.e. transmission, reflection and time delay (r) responses) of uniform polymer optical fiber (POF) Bragg gratings has been investigated. In addition to the temperature dependence, the effects of grating strength (kLg) and fiber index modulation (n)...

| description | The thermal dependence of the spectral response (i.e. transmission, reflection and time delay (r) responses) of
uniform polymer optical fiber (POF) Bragg gratings has been investigated. In addition to the temperature
dependence, the effects of grating strength (kLg) and fiber index modulation (n) have been investigated. Besides
high capability of tunable wavelength due to the unique large and negative thermo-optic coefficient of POF, the
spectral response for POF Bragg gratings show high stability and larger spectrum bandwidth with temperature
variation compare with the silica optical fiber (SOF) Bragg gratings, especially with the increase of the kLg value. It
was found that by increasing kLg, the peak reflectance value increases and the bandwidth of the Bragg reflector
become narrower. Also it’s shown by increasing the kLg value, r deceasing significantly and reach its minimum
value at the designed wavelength (B). Furthermore, the r for POF Bragg gratings is less than that for SOF Bragg
gratings at the same value of kLg. Also it’s found that the peak reflectivity value increases to around 60% when the
n value increases from 110-4 to 510-4. |
