“…The glasses used for this purpose are doped with the rare-earth ions [54][55][56][57][58][59][60]. On the basis of gradient planar waveguide structures the optical sensors are also produced [61][62][63][64][65]. In the gradient waveguides produced by ion exchange in glasses doped with semiconductors the nonlinear effects are also observed [66][67][68].…”

Abstract. This paper presents the technological aspect of application of the ion exchange method in producing gradient refractive index in glass. The possibility of predictable and repeatable producing of the changes in glass refraction with the use of this method has been presented, as well as the method of in situ control of the process of diffusion doping of glass based on the measurement of the temperature. This method is based on simultaneous (to the carried process) solving the nonlinear diffusion equation modeling the spatio-temporal changes in normalized concentration of the admixture ions in glass. For this purpose the knowledge of temperature characteristics of diffusion coefficients of exchanged ions is used. The result of such control of diffusion processes is information on the current (temporary) refractive index profile of the resulting waveguide. The presented method of control has been confirmed by experimental results, which concern modeling and measurements of planar waveguide structures of slab type. The proposed methodology can also be used to control the diffusion processes of producing another type of two-and three-dimensional gradient structures. According to the author's knowledge the method mentioned above has not been described in literature before.

“…Several sensor concepts have been demonstrated using ion-exchanged waveguides, 163 many using guided-wave interferometer structures, which can be used for example in distance or refractive index measurements. There are also sensor concepts utilizing multimode waveguides, 164 which can provide cost advantages. One main category is chemical sensors, 165 probing the sample substance with light propagating in waveguides.…”

Abstract. We review the history and current status of ion exchanged glass waveguide technology. The background of ion exchange in glass and key developments in the first years of research are briefly described. An overview of fabrication, characterization and modeling of waveguides is given and the most important waveguide devices and their applications are discussed. Ion exchanged waveguide technology has served as an available platform for studies of general waveguide properties, integrated optics structures and devices, as well as applications. It is also a commercial fabrication technology for both passive and active waveguide components. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).

This chapter presents the chosen aspects of the ion exchange technological method. Results of research refer to the refractive index profiles of planar waveguides produced by the ion exchange method in various glasses. All refractive index profiles were determined by measuring the effective refractive indices of the waveguide modes. In the first part of this chapter the processes of electrodiffusion doping sodalime glass with silver ions has been described. The second part contains a description of the two measurement methods allowing to estimate the equilibrium concentration basing on the example of the concentration of sodium in soda-lime glass. The third part describes the phenomenon of stress birefringence arising in borosilicate BK-7 glass doped with potassium ions K + . The fourth section presents the results of research on the real-time control of ion exchange diffusion processes. The results confirming the validity of this idea with examples of soda-lime glass (Menzel-Gläser company), BK-7 (Schott company) and Pyrex (Borosilicate 33 of Corning company) doped with Ag + silver ions and K + potassium ions are also presented here.
