Polarization-Independent/Converging-Beam Optical Isolator (XFSI)
This innovative polarization-independent free-space optical isolator for converging light fills a gap in polarization-independent converging-beam applications. Designers can simplify conventional two-lens collimated-beam designs into more stable, mature single-lens converging-beam designs. It also withstands higher optical power than polarization-dependent isolators, allowing replacement in high-power applications such as CPO CW DFB laser packages while retaining the converging-beam structure of existing polarization-dependent designs and avoiding processing and yield issues associated with two lenses. Figure one: conventional polarization-independent collimated-beam free-space isolator design. Figure two: Furuibeisi polarization-independent converging-beam free-space isolator design (XFSI).

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.
