| 英文摘要 | A small module contains means for converting an electrical signal to a correspondingly modulated light signal on an optical fiber. Frequency of the signal can range from D.C up to many gigahertz. A semiconductor laser diode is mounted on a high thermal conductivity substrate on a thermoelectric cooler for controlling laser temperature. The optical fiber output is soldered to the laser substrate with an end in alignment with the laser junction. A laser bias circuit is on a connection substrate adjacent to the laser substrate. A connection substrate also includes a deposited signal lead line connected to the bias circuit by an impedance matching means. Electrical signals from the pin of an external coaxial connector are coupled to the lead line. The laser bias circuit and signal lead line are electrically connected to the laser diode by wires between the connection substrate and the laser substrate. A photodiode in the module in the light path from the laser provides a control signal. |
