L-Band Three-Port Polarization-Independent Optical Circulator
The Shanghai HanyuL-band (1565–1610nm) three-port polarization-independent optical circulator provides unidirectional optical transmission. The source describes incident light as exiting port1 and then exiting port2, while light returning through port2 exits port3, providing unidirectional transmission similar in function to an optical isolator. Three-port circulators are available at wavelengths including1310nm,1550nm (C-band) and C+L band. The company offers high performance at low cost for fiber-optic sensing, dispersion-compensation modules, fiber filters and research. The polarization-independent design processes the two orthogonal polarization states in single-mode fiber separately to maintain polarization independence.

A solid-state laser is one of the most common and reliable laser types used in modern industry, medical equipment, and scientific research. Unlike gas or fiber lasers, it uses solid materials as its gain medium to generate stable, high-brightness laser beams. Thanks to its high precision, long lifespan, and compact structure, solid-state lasers have become a mainstream solution for high-precision laser processing and optical systems.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems.
