The paper presents technology of 1xN waveguide splitters based on multimode interference (MMI) structures made by ion exchange in glass. A method of modal field interference examination in MMI structures, using fluorescence of the substance covering the MMI section is proposed. Testing investigations are carried out for MMI structures made by K+↔Na+ ion exchange process in glass. Studies of technology of 1xN waveguide splitters based on MMI structures made by ion exchange in glass are also presented.
In the paper are presented theoretical and experimental studies of multimode interference structures made by K+↔Na+ ion exchange process in glass. Investigations concerned the self-imaging phenomena for symmetrical and paired interference. The new method of mode field interference examination is proposed, using fluorescence of substance covering the MMI section.
In the paper, a new concept of the 1×2 waveguide beam splitter has been presented, on the basis of gradient multimode interference structures made by Ag+-Na+ ion exchange in glass with an arbitrary power splitting ratio at the output. The beam splitter, working in Mach-Zehnder configuration, consists of two asymmetrical MMI sections operating as 3dB couplers joined by monomode waveguides of different width. The operating characteristics of the 1×2 beam splitters have been determined for different geometry configurations of waveguides joining the MMI section. Self-imaging phenomena in MMI make possible to use in one of interferometer arm the multimode waveguide.
In the paper are presented numerical studies of gradient index optical splitters made in a multimode interference technology by Ag+ $ARLR Na+ ion exchange process. The influence of geometrical parameters of multimode interference structure and technological process parameters is examined in numerical simulations and gradient index optical waveguide splitters and Mach-Zehnder interferometers are proposed. The possibility of using MMI sections as transducers of distributed sensors is discussed.

The present paper discusses theoretical and experimental research on the planar difference interferometer produced with the use of planar technique on a glass substrate plate (planar interferometers) in view of its application in the system of phase-polarization sensors of basic physical quantities.
In this paper are presented numerical optimizing investigations of planar polarimetric interferometer made by K+-Na+ ion exchange in glass for sensor applications. Two cases are considered: phase modulation of guided light waves caused by refractive index changes of the waveguide cover for applications of the polarimetric interferometer as refractometers or chemical sensors, and phase changes induced by nanometers of a dielectric layer separated from the waveguide by an air gap of the width below wavelength of light for using of the polarimetric interferometer as an acoustical transducer and pressure or displacement sensor.
