  • 分布反馈型

例句与用法

  • Dfb - ld distributed feedback ld
    分布反馈型
  • In present commercial wdm systems , distributed feedback las ers ( dfb - ld ) are widely used as a single - mode tight source
    在目前的wdm系统中,分布反馈半导体激光器( dfb - ld )已被广泛地用作单频光源。
  • Based on the rate equation and the temperature characteristic of the ld , the temperature control object model and the temperature control error of dfb - ld are analyzed . then the power and wavelength output characteristic is farther analyzed
    首先从ld的温度特性入手,分析了分布反馈式ld ( distributefeedbacklaserdiode , dfb - ld )的温度控制误差、温度控制对象。
  • However , the emission wavelength of a dfb - ld needs to be carefully turned on the predetermined wavelength grid by adjusting both laser temperature and bias current . furthermore , dfb - ld has such drawbacks as a relatively large variation of the lasing wavelength with ambient temperature ( ~ 0 . 1nm / c ) which restricts its application in dwdm systems
    然而dfb - ld的激射波长受温度( 0 . 1nm )和偏置电流的影响较大,只有通过调节dfb - ld的温度和偏置电流,其激射波长才能被调谐在预置的波长处。
  • Usually , it is thought that the lasing wavelength of a fgesl is locked at the bragg reflection wavelength of fiber grating ( fg ) . owing to a relatively small dependence of the reflection spectrum of fg on ambient temperature ( - 0 . 01nm / c ) , the lasing wavelength of a fgesl is thought to behave more stable than that of a dfb - ld
    由于fgesl的激射波长主要由光纤光栅( fg )的布拉格波长确定,因此选择具有合适布拉格波长的fg就能使fgesl的激射波长处于预置波长处;同时,由于fg的布拉格波长受温度变化的影响相对较小( 0 . 01nm ) ,因此fgesl与dfb - ld相比具有更高的温度稳定性。
