Cylindrical, Ring-Electrode KD*P Electrooptic Modulator
Abstract:
We report the development of an electrooptic cell consisting of a cylindrical sample of Z-cut KD*P with a ring-electrode geometry for applying voltage to the crystal. Theoretical analysis and experimental results demonstrate that this cell design results in high transmission uniformity across the cell aperture and subnanosecond switching capability. Compared with cell of conventionaldesign, the new cell permits an order-of-magnitude improvement in transmission uniformity as well as improved switching speed.

Potentiometry: Types of Electrodes
The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...
