Abstract
Embodiments of the present disclosure relate to an optical transceiver, and more particularly to an optical transceiver that includes an optical system capable of simultaneously performing both functions of a reflector and a focusing lens, does not cause Fresnel reflection through an integrated optical system made of the same medium, and furthermore facilitates optical alignment.
Claims10
An optical transmitter including a transmitter body (220), wherein the transmitter body (220) comprises
- a transmitter convex lens (222) formed in a downwardly convex shape on a lower surface of the transmitter body (220), facing a light source (210) and collimating incident light emitted from the light source (210);
- and
- a transmitter reflective curved surface (224) formed as a reflective curved surface on one surface of the transmitter body (220), reflecting parallel rays collimated by the transmitter convex lens (222) to focus light beams reflected from the curved reflective surface into an optical fiber (100),
- wherein the transmitter convex lens (222) and the transmitter reflective curved surface (224) are integrally formed in the transmitter body (220) using a material having the same refractive index,
- wherein a cross section of the optical fiber (100) is attached to a transmitter vertical surface (226) of the transmitter body (220) and the optical fiber (100) is arranged to be inclined with a tilting angle with respect to a vertical direction of the transmitter vertical surface (226), and
- wherein the tilting angle is in a range of 5° or more and 10° or less.
