The fluorescing sensor is based on the change in fluorescence intensity of a buffered pH indicator solution entrapped in silicone rubber. Exposure to ammonia increases the pH of the trapped solution; this increases the fluorescence intensity, which is monitored via an optical fibre bundle. Ammonium

## Abstract An integrated electroβoptical Eβfield sensor using a protonβexchanged LiNbO~3~ MachβZehnder (MβZ) interferometer with a combined antenna and modulator electrode structure is designed and fabricated to improve the sensitivity and bandwidth of the device. The experimental results show tha
## A novel Ti:LiNbO, integrated optical channel waveguide toxic gas sensor is demonstrated, and gas sensing is observed for NO, by means of the detection of an optical output. The device is constructed in a Mach-Zehnder interferometer geomety with a Langmuir-Blodgett (LB) film cover with chemically
