High-Resistivity Silicon Lens
Apart from synthetic diamond, high-resistivity silicon is the only isotropic crystalline material suitable over the extremely broad range from the near-infrared (1.2μm) to millimeter waves (1000μm). It is considerably less expensive to grow and process than diamond and can be made in large sizes for THz electronic components. High-resistivity float-zone silicon (HRFZ-Si) is available for terahertz applications, maintaining approximately 50-54% transmission in the THz band to wavelengths of 1000μm, and even 3000 or 8000μm.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
