temperature characteristics of y waveguide half-wave voltage
y waveguide is also known as y-type waveguide lithium niobate crystal , which is a ieal optical phase modulator, which incorporates the Y-splitter, polarizer, and optical modulator as a whole.Due to the high degree integration, small size, not only reduces the volume of FOG, but also improve the stability and reliability, now it has become the key device in the development process of high precise FOG.The Y waveguide half-wave voltage can be written as:
