  • Patent number: 12169314
    Abstract: A short-waveband active optical component based on a vertical emitting laser and a multi-mode optical fiber has an emitting end and a receiving end. In the emitting end, multiple VCSELs generate multiple optical signals of different wavelengths, and multiple photodiodes in the receiving end receive the optical signals emitted by the VCSELs. Both ends use a focusing lens array to collimate and focus the optical signals A Z-block-shaped prism performs a light combining function at the emitting end, while another Z-block-shaped prism performs a light splitting function at the receiving end. Both ends use a focusing lens for collimating and focusing the optical signals at ends of a multi-mode optical fiber, which is used for transmitting the optical signals generated by the VCSELs. The short-waveband active optical component has a small size and a high transmission rate.

  • Publication number: 20240076231
    Abstract: A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.

The optical fiber array assembly and a collimating lens assembly are positioned, assembled, and fixed in the housing. The light output surface of the optical fiber array assembly is installed near the focal plane of the collimating lens assembly. By adjusting the distance between the optical fiber array and the collimating lens, the high-precision collimated output beams from multiple optical fibers can be realized simultaneously. The fiber array can be packed and assembled with dozens or hundreds of fibers with high density. The fiber arrangement has the characteristics of adjustable density, high precision spacing and high reliability. The collimating lens includes at least one spherical or aspherical lens, which can achieve minimal aberration in different fields of view through optical design optimization.

The laser oscillator module consists of a seed laser and its collimating system, and the laser amplifier module consists of a laser pump module and a laser gain element. The seed laser with high beam quality is collimated by collimation system, then input into the gain element; the pump laser is pumped into the gain element via end pump or side pump mode. The seed laser beam transmits into the gain medium and is reflected by the interface several times with the “Zigzag” path, which makes the seed laser fully gained and amplified, finally achieving high power and high beam quality laser output. In this present disclosure, the laser gain material is doped with different rare-earth ion concentrations and processed into different shapes.
