“…The sensitivity is mostly determined by the optical power propagating in the sensing region, and various techniques of coupling as much incident optical power into the working region as possible are always the interest of researchers. The commonly used coupling techniques are end-fire coupling 7 , prism coupling 8 , grating coupling 9 , and tapered film coupling 10 . Recently, a symmetrical metal-cladding optical waveguide (SMCOW) structure was proposed by Li 11 et al The SMCOW structure has attracted much attention since the incident wave is coupled directly from free space into symmetrical metal-cladding optical waveguide, which makes efficient coupling possible in guided-wave optics experiment and devices.…”

The analysis of the temperature property of sensors based on symmetrical metal-cladding optical waveguide (SMCOW) is focused on analyzing the temperature property of reflectivity of SMCOW sensors, which is theoretically studied with single-factor investigation under spectral and angular interrogation scheme. There are mainly four factors influencing the temperature dependence of reflectivity, it is the temperature dependence of refractive index and thickness of guiding layer, along with the temperature dependence of the metal film thickness and metal-dielectric function. The simulation result shows that the effect of temperature on the reflectivity of SMCOW is mainly attributed to the temperature dependence of refractive index and thickness of guiding layer；on the contrary, the temperature properties of metal film hardly contributes to the influence of temperature on the reflectivity. Based on the analysis, the sensitivities of SMCOW with guiding layer of different optical glasses are computed under both spectral and angular interrogation. This paper is supposed to provide direction in designing temperature-sensitive SMCOW structure sensors.

“…Thus, an isotropic planar waveguide can be excited by a gaussian beam through its direct focussing on an exposed cross-section [1,2], by a plane wave incident on a waveguide through air gap [3][4][5][6][7][8] and by a linear source [11].…”

Displacing a linear source exciting the waveguide along an arbitrary fixed direction to infinity one can create the conditions in which the waveguide is excited by a plane wave. The nature of the excited field in a waveguide is complicated. On the upper plane of the waveguide x +l one always deals with the radiation mode whereas on the lower boundary of the waveguide x = -l one can deal with the radiation mode or the surface-type wave.

The theoretical investigation of planar dielectric waveeixide affected by electric field is presented herein. The electric field modifies refractive index of the waveguide only by means of Pockels effect. As a result, distorted waveguide causes radiation losses for guided electromagnetic waves in different way for TE and TM modes. The model of step index waveguide was assumed and calculation of transmission characteristics for TE and TM modes with the Y -cut lithium niobiate plate was done. As a conclusion, some practical applications of electrooptically perturbated waveguide are discussed.
