In order to overcome the well-known limitation of temperature instability in Bragg grating waveguide sensors, a temperature insensitive open-top ridge waveguide refractometer is developed by using a cladding mode resonance as a temperature reference.

A highly sensitive waveguide Bragg grating (WBG) sensor for measuring small changes of the refractive index of the surrounding liquid is presented. By using an open top ridge waveguide with a small core, the evanescent field interaction of the guided

A method for rapid compensation of high intrinsic birefringence in plasma-enhanced chemical vapor deposition (PECVD) based planar waveguides is presented. The intrinsic waveguide birefringence is compensated by a large UV induced opposite birefringen

The TeX glasses based on the glass-forming ability of the TeX (X = Cl, Br, I) systems have potential low losses in the 8–12 μm region. Different glass compositions in the TeSeI and TeSeAsI systems have been chosen for fibre drawi

Optical fibers have been obtained from the Te Se Br and Te Se I systems. Fibers having a composition of Te3Se4I3 show an attenuation less than 2 dB/m at several wavelengths. Preforms having a core-cladding structure have also been drawn into fibers a

Experimentally, in the open-top ridge waveguides, the sensitivities of core and cladding resonances to the surrounding medium's refractive index are different while the temperature sensitivities are similar. Based on these characteristics, a temperat

Bragg grating refractometers have been previously disclosed by other authors but sometimes suffer from temperature instability due to well know grating characteristics. In order to overcome this limitation, a temperature insensitive refractometer is

Optical Bragg grating sensors based on side polished or etched waveguides have been demonstrated for the measurement of refractive index [1, 2, 3, 4]. However, these devices typically exhibit polarization dependent behavior for index values around 1.

The Young's modulus, E, and the fracture toughness, KIc, were investigated for the glass series Te2Se7−xAsxI (x = 0−6), Te3−xSe6AsxI (x = 0−2.5), and Te5−xSe3AsxI2 (x = 0−4), respectively. For the glass series Te2Se7−xAsxI, E increased
