The precursor gel was prepared by sol-gel process from siloxane-modified methacrylate monomer. The molecular structure characterization results show the formation of inorganic networks within the precursor gel, which further undergoes the formation of organic-inorganic polymer network by photopolymerization. The laser interference was performed by using the frequency-tripled output of nanosecond Nd-YAG laser. The fabricated DFB gratings exhibit photopumped lasing actions with high consistency between the grating periodicity (between 380 and 1030nm) and the lasing wavelength, which appears at the wavelength of the second-order Bragg reflection. The atomic force microcopy measurements clearly show the formation of surface relief (corrugated) structure in those gratings. The mechanism of surface relief formation is attributed to a fast photo-induced swelling process, which is unique property belonging to this kind of hybrid polymer precursor gel. © 2011 John Wiley & Sons, Ltd.[/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]Atomic force,Bragg reflection,Distributed feedback,Distributed feedback grating,Hybrid polymers,Inorganic network,Laser Interference,Lasing action,Lasing wavelength,Methacrylate monomers,Nd-YAG lasers,Organic inorganic polymers,Photo-induced,Polymer dye lasers,Second orders,Short-pulse lasers,Sol-gel hybrids,Structure characterization,Surface relief formation,Surface reliefs,Swelling process[/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]Photopolymerization, distributed feedback grating,Photopumped laser,Polymer dye laser,Sol-gel hybrid polymer[/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][/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/10.1002/pat.2039[/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]
