• Synthesis and characterization of transparent photonics glasses without hazardous elements


• Very small birefringent (photoelastic) oxide glasses for polarization-controlling optical materials


• Structural analysis in functional oxide glasses

We have continuously studied an oxide fiber which can utilize for an optical fiber typed current sensor. The important points of the device are hazardou element free, such as lead, and are possessing a property of very small photoelastic constant of consituent oxide glass.
