“…Currently, in our laboratory the converter has been successfully implemented in several integrated optical sensing platforms, such as a fully integrated optical polarimeter [14] and a differential absorption sensor [23]. In these circuits, the converters are used for partial conversion of a launched TE mode into a TM-polarized mode and also for obtaining the interference of TE-and TM-polarized zeroth order modes.…”

“…Due to the specific application, which in our case is an integrated optical sensor of 0733-8724/01$10.00 ©2001 IEEE specific type [14], the converter presented here is designed for a wavelength of 655 nm. However, the design methodology, based on an optimization with respect to device reproducibility, can be generally applied for every operation wavelength.…”

Abstract-A passive polarization converter has been realized in silicon oxynitride (SiON) technology. The device is a grating assisted codirectional coupler consisting of segments of asymmetrically etched ridge waveguides. By using a double-masking technique, the fabrication of the device is tolerant with respect to the alignment of the required masks. Conversion efficiencies up to 0.98 (TE TM and TM TE) and insertion losses of 3 dB/cm have been measured. Using 2-D beam propagation method simulations, an observed beat pattern in the converter could be explained as due to a leaky mode, which is captured in the grating structure.

“…The range of application of gas sensors based on systems of integrated optics comprises many domains, from industry to medicine and protection of the environment [8][9]. An advantage of optical waveguide sensors, including photonic sensors is, among others, a wide group of gaseous substances which can be determined by means of them [8,10]. Most important, however, is the fact that optical and photonic sensors are resistant to disturbances of electromagnetic fields and can operate in explosive environments [11][12].…”

The paper presents the results of investigations concerning the application of zinc oxide -a wideband gap semiconductor in optical planar waveguide structures. ZnO is a promising semiconducting material thanks to its attractive optical properties. The investigations were focused on the determination of the technology of depositions and the annealing of ZnO layers concerning their optical properties. Special attention was paid to the determination of characteristics of the refractive index of ZnO layers and their coefficients of spectral transmission within the UV-VIS-NIR range. Besides that, also the mode characteristics and the attenuation coefficients of light in the obtained waveguide structures have been investigated. In the case of planar waveguides, in which the ZnO layers have not been annealed after their deposition, the values of the attenuation

“…The said effects bring about the change of effective refractive in− dexes of modes propagating in the structure. The changes of effective refractive indexes can be measured by the applica− tion of the interferometers of Mach−Zehnder [4,5], Young [6,7] and with a polarimeter [1,[8][9][10] or grating couplers [3,[11][12][13][14][15][16][17][18]. In chemical and biochemical measurements, surface plasmon resonance sensors are also applied [19,20].…”

The paper presents input grating couplers to be applied in planar evanescent wave sensors. Waveguide films SiO2:TiO2 were obtained using the sol-gel method, and grating couplers with a groove density of 1000 g/mm and 2400 g/mm were produced using the method of master grating embossing in sol film. The influence of refractive index of the cover on incoupling angles was presented. Basing on the experimental results, detection limits involving the changes of effective indexes and refractive indexes of the cover for the investigated planar structures were determined. Sensor structures with the couplers having a groove density of 1000 g/mm enable to detect minimum changes of the effective index below 3.3×10−7 and to detect minimum changes of refractive index of the cover below 2.3×10−6. Detection limits for the structures with couplers having the groove density of 2400 g/mm are over twofold higher.
