Latest Patents

Dong Lin holds a patent for a "High isolation and low insertion loss optical isolator." This innovative device features an optical isolator that provides high isolation and low insertion loss across a wide bandwidth. The design includes an input fiber collimator, isolator cores, and an output fiber collimator connected in sequence along an optical path. The acute ends of the wedge surfaces of lenses and fiber heads of the collimators are polished to create small platforms. The Faraday crystals within the cores are optically active and vary in wavelength, while the birefringent wedges differ in wedge angle. Notably, the optical axis of the birefringent wedges at the emitting end of the first core is perpendicular to that of the second core. This two-stage design of Faraday crystals enhances isolation performance across a broader bandwidth. Additionally, a small-spot collimator design minimizes coupling loss, ensuring stable performance and high reliability.
