Abstract :
We demonstrate the concentration measurement of liquid by using silica high-mesa waveguide for the first time. It proves that a certain portion of the propagation light has profiled out actually from the waveguide. Moreover, the concentration measurement of 2% ethanol was also confirmed successfully.
