  • Publication number: 20250044505
    Abstract: The present application discloses a light beam scanning system. The system comprises a beam splitting apparatus, an optical waveguide array, a light beam combining member, a light beam adjusting apparatus and a phase adjusting apparatus. The beam splitting apparatus receives a laser light beam, and divides the laser light beam into a plurality of sub-beams and then emits the sub-beams; the optical waveguide array is used to receive the plurality of sub-beams and transmit the plurality of sub-beams to a predetermined waveguide emergent end; the light beam combining member is connected to the optical waveguide array; the light beam adjusting apparatus is used to expand and collimate the light beam emitted from the light beam emergent surface to form a scanning light beam; the phase adjusting apparatus is used to adjust the relative phase distribution of the sub-waveguides.

  • Publication number: 20240266806
    Abstract: A laser capable of reducing the difficulty of a wavelength tuning process, a fabrication method therefor, and a laser device. The laser comprises: an active light-emitting structure used for emitting light; a silicon-based structure which is bonded to the active light-emitting structure, and which comprises a silicon-based waveguide and at least two composite gratings, wherein the composite gratings are opposite to the active light-emitting structure and are formed in the silicon-based waveguide. Each composite grating comprises one primary grating and a plurality of secondary gratings, the secondary gratings are periodically arranged to form the primary grating, and the primary gratings in at least a portion of the composite gratings have different grating periods from that of the primary gratings in other composite gratings. The silicon-based structure and the active light-emitting structure form at least two laser units, and each laser unit corresponds to one composite grating.

  • Patent number: 9946039
    Abstract: An optical transceiver module includes an optical fiber and an optical fiber positioning structure that fixes the optical fiber. The optical fiber positioning structure includes a first positioning part that fixes the said optical fiber, and a first supporting part that fixes the first positioning part on a case of the optical transceiver module. The first positioning part includes a first end face and a second end face opposite to one another, and a first through-hole that connects the first and second end faces. The inner diameter of the first through-hole is substantially equal to the diameter of the optical fiber, and the optical fiber is fixed within the first through-hole. The first supporting part includes an accommodating portion for accommodating the first positioning part. The first positioning part is fixed in the accommodating portion.
