In this paper, we report the fabrication of tapered optical fiber by employing laser induced photopolymerization(LIP) technique from hybrid organo-siloxane polymer precursor. This precursor was prepared by the sol-gel method for creating the inorganic cross-links. The photopolymerization process then made the organic cross-links and transformed it into the solid phase. The taper structure formation was strongly dependent on the laser power and time duration. A typical condition for taper structure formation was the laser power of 2 μW and the fiber drawing speed in the range of 20 μm/s – 40 μm/s.The resulted tapers lengths were around 1.5 mm-5.5 mm with the diameter around 100 μm at the beginning of the taper and less than 5 μm at the end of the taper. The optical propagation and evanescent wave profile in this kind of tapered optical fiber was also studied computationally by using Finite Difference Time Domain (FDTD) method.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Evanescent wave,Hybrid polymers,Laser induced,Siloxane polymers,Taper structure,Tapered optical fiber sensors,Tapered optical fibers,Wave formation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]evanescent wave,Hybrid polymer,optical waveguide,tapered optical fiber sensor[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors acknowledge the support from Program Riset dan Inovasi ITB 2012 and Program Beasiswa Tesis dan Disertasi (LPDP).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1127/1/012020[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
