Examples
- As the first stage of the system , its gain , noise figure ( nf ) and linearity directly take effect on the whole circuit
由于是整個(gè)電路系統(tǒng)的第一級(jí),因此其增益,噪聲,線性度等直接影響整個(gè)電路系統(tǒng)的性能。 - 4 . the lpfgs are used in single wavelength er - doped fiber amplifiers ( edfas ) as a spontaneous emission noise ( ase ) filter , and the gain of the edfa is increased by 7db and the noise figure ( nf ) is decreased by 0 . 5db , for the first time
4 、成功研制了摻鉺光纖放大器,首次將高頻co2激光脈沖寫入的長(zhǎng)周期光纖光柵應(yīng)用到摻鉺光纖放大器中作為自發(fā)輻射噪聲濾波器,使edfa的增益提高了7db 、噪聲系數(shù)降低了0 . 5db 。 - 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(qū)結(jié)構(gòu)制備出偏振不靈敏半導(dǎo)體光放大器，并在0 - 200ma注入電流范圍內(nèi)獲得33nm的3db帶寬，在不同信號(hào)波長(zhǎng)，不同信號(hào)功率0 - 200ma的注入電流范圍內(nèi)，偏振相關(guān)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(dá)10db ，無損操作電流為50 - 70ma ，消光比達(dá)50db以上，而噪聲指數(shù)則低于8db ，最小可達(dá)4 . 6db 。
