Bragg’s grating coupler in planar optical sol-gel waveguides
نویسندگان
چکیده
The aim of our investigation was to develop a technique of producing Bragg’s grating couplers on planar waveguides obtained by means of the sol-gel technique. Introducting a light beam into the waveguide structure is in the case of planar optical systems always an essential technological problem, requiring simple and reproducible solutions without extending the waveguide structure too much. The paper deals with the technology of producing grating couplers by impressing the pattern of the network while forming the planar waveguide structure applying the sol-gel method. The results of investigation on grating couplers obtained in such a way have also been presented. Attention has been drawn to the possibility of using such structures in optoelectronic sensors, particularly gas sensors, including sensors of toxic gases.

متن کاملAn elastomeric grating coupler
We report on a novel nondestructive and reversible method for coupling free space light to planar optical waveguides. In this method, an elastomeric grating is used to produce an effective refractive index modulation on the surface of the optical waveguide. The external elastomeric grating binds to the surface of the waveguide with van der Waals forces and makes conformal contact without any ap...

Ridge and buried channel waveguides were fabricated on different substrates such as SiO2-on-Si, Si, glass wafers and Printed Circuit Boards by a sol-gel processing together with a photolithography process using photopatternable hybrid sol-gel materials. Thick sol-gel films of up to 100 microns were developed using a modified sol-gel process and ridge waveguides with vertical smooth sidewalls we...
