A small integrated free space circulator, comprising a first polarizing beam splitter (), a half-wave plate (), a Faraday rotating plate (), a beam splitter (), a quarter-wave plate (), and a pair of reflective plates (), wherein the first polarizing beam splitter (), the half-wave plate (), the Faraday rotating plate (), and the beam splitter () are sequentially arranged, the quarter-wave plate () and the reflective plate () are sequentially attached to a side surface of the first polarizing beam splitter () adjacent to the half-wave plate (), and the reflective plate () is arranged on a side surface of the beam splitter () adjacent to or opposite to the Faraday rotating plate (); when the reflective plate () is arranged on the side surface of the beam splitter () opposite to the Faraday rotating plate (), the reflective plate () partially covers the side surface of the beam splitter () opposite to the Faraday rotating plate (). By means of an organic combination of optical elements such as the polarizing beam splitters (), the wave plates (), the Faraday rotating plate (), the reflectors (), and the birefringent crystal (), the device has advantages such as small volume, high integration, easy production, and low cost, and has a good market prospect.

Small integrated free space circulator

A vertical cavity surface emitting laser (VCSEL)-based free space active optical transceiver component includes a transmitter and a receiver. The transmitter includes first VCSELs, at least one first photodiode, a first focusing lens array or optical system (), and a first printed circuit board. The receiver includes second photodiodes, at least one second VCSEL, a second focusing lens array or optical system, and a second printed circuit board. The transmission and reception of a short/medium-distance free space (wireless) high-speed optical communication signal can be implemented, and a single-channel transceiving rate may reach 10 Gbps or higher. The component may be used for implementing a free space high-speed signal transmission function in a short/medium-range high-definition multimedia interface (HDMI) device.
