  2. In order to measure the characteristics of such semiconductor optical amplifier, we adopted a set of measurement system. this measurement system can be used to measure the characteristics of all kinds of active or inactive optical passive components. such device presents good polarization insensitivity ( < 0. 9db ), wide 3db bandwidth ( > 33nm ) at 0 - 200ma and different input signal light wavelength and power, the maximum fiber - to - fiber gain of 10db, lossless operation current of 50 - 75ma for different input signal light wavelength and power, large extinction ratio ( > 50db ) and lower noise figure ( nf ) ( < 8db )

    與張瑞英博士一起，首次利用該種有源區結構制備出偏振不靈敏半導體光放大器，並在0 - 200ma注入電流范圍內獲得33nm的3db帶寬，在不同信號波長，不同信號功率0 - 200ma的注入電流范圍內，偏振相關損耗均《 0 . 9db ，在耦合差損為7db / facet的條件下，最大fiber - to - fiher增益達10db ，無損操作電流為50 - 70ma ，消光比達50db以上，而噪聲指數則低於8db ，最小可達4 . 6db 。
  3. The products of hg genuine cover semiconductor laser and detector chip, active device, transceiver that are widely applied in communication and optical sensors

    公司產品包括半導體鐳射器和探測器管芯、光電子器件、光收發模組三大系列，主要應用於數字、模擬通信以及光傳感等領域。
  4. With these optical transceivers, the workstation on the shore can receive the synchronization signal for synchronization demodulation of pgc and controls the long - distance photoelectric modules under water. in this thesis, a long - distance optical transceiver is designed to meet the above requirements. beginning with the principle of optical communication, characteristics of the basic optical active device are summarized firstly

    為了實現pgc信號的同步解調與遠程水下光電模塊的監控，岸基工作站與水下光電模塊需要通過光收發一體模塊進行低速率、無中繼的雙工通信，因此本課題的主要工作是進行遠程水下光收發一體模塊的設計與實現。
