Optical coupling element, arrangement, and transceiver

Abstract

An optical coupling element is configured to be positioned between and optically couple a first optical component configured to transmit a light beam, and a second optical component configured to receive light. The optical coupling element comprises a glass coupler body having a receiving side surface and an opposite transmitting side surface. The glass coupler body comprises a converging member configured to reduce divergence of light entering the glass coupler body via the receiving side surface; and a coupling waveguide extending within the glass coupler body between the converging member and an output facet on the transmitting side surface and being configured to transmit light from the converging member to the output facet.
