Latest Patents

One of his latest patents is titled "Anti-torsion solid-core polarization-maintaining photonic crystal fiber based on anisotropy of stress distribution." This innovative fiber design includes a cladding with an inner layer featuring multi-layer air holes that construct optical properties. The arrangement of micron-size air holes along the x-axis produces form birefringence, while the outer layer's multi-layer air holes are arranged radially along the y-axis. This unique configuration allows the fiber to possess anti-torsion capabilities, reducing the non-reciprocal phase difference generated by the magneto-optic Faraday Effect.

Another notable patent is the "Hollow-core antiresonant fiber with nested supporting rings and its design method." This fiber structure consists of a core surrounded by alternating silica and air antiresonant rings, along with nested supporting rings. The design offers low confined loss, large bandwidth, and excellent bending characteristics, significantly expanding the application fields of hollow-core antiresonant fibers.
