    摘要: A compact optical transceiver including a ceramic mounting block 1, with a laser diode 3 abutting a first end of the mounting block for generating light of a first wavelength. A GRIN lens 5, mounted to the mounting block, then receives and focuses the generated light to an optical fiber 13 which is attached to the compact optical transceiver. A dichroic substance 7 acts as a beamsplitter by passing light of a first wavelength and deflecting light of a second wavelength. The dichroic substance 7 is coated on a glass plate, which is mounted in a first angular groove of the mounting block. The beamsplitter 7 receives and passes the generated light of the first wavelength which has been focused by the GRIN lens 5. From a remote transmitter, light of a second wavelength is then transmitted through an optical fiber 13, to the compact optical transceiver from a direction opposite that of the light generated by the laser diode 3. The light transmitted from the optical fiber 13 is then transmitted and output through ferrule 11, attachable to the optical fiber and attached in a second, V-shaped, groove of the ceramic mounting block 1. The light of the second wavelength is output to the beamsplitter 7 and is deflected through a bore hole 21 in the ceramic mounting block to a detector 9 abutting the bottom of the mounting block. Optionally, a blocking filter 15 can be included between the detector and the optical fiber end face for blocking light of any wavelengths different from the first and second wavelengths, from reaching the detector 9.

    摘要: A compact optical transceiver including a ceramic mounting block 1, with a laser diode 3 abutting a first end of the mounting block for generating light of a first wavelength. A holographic optical element (HOE) 5 is positioned adjacent laser diode 3 and acts as a hologram lens which receives and focuses the generated light to the end face of an optical fiber 13 which is attached to the compact optical transceiver. A glass element 7 is mounted on the mounting block between the diode and the optical fiber end face, and includes dichroic substance 8 coated to the fiber-proximate side of the glass element 7 and acts as a beamsplitter by passing light of a first wavelength and deflecting light of a second wavelength. The glass element 7 is mounted in an angular positioning groove of the mounting block. The beamsplitter 8 receives and passes the generated light of the first wavelength which has been focused by the HOE 5. From a remote transmitter, light of a second wavelength is then transmitted through an optical fiber 13, to the compact optical transceiver from a direction opposite that of the light generated by the laser diode 3. The light transmitted from the optical fiber 13 is then transmitted and output through ferrule 11, attachable to the optical fiber and attached in a second, V-shaped positioning groove of the ceramic mounting block 1. The light of the second wavelength is output to the beamsplitter 8 and is deflected through a bore hole 21 in the ceramic mounting block to a detector 9 abutting the bottom of the mounting block. A blocking filter 15 can be included for blocking light of wavelengths other than the first and second wavelengths from the detector.
