外调制 meaning in Chinese
external modulation
space modulation
Examples
- It can be divided into out external modulation and inner modulation
脉冲调制激光器分为外调制和内调制两大类。 - Especially , linbo _ 3 optical modulators , using m - z waveguides and traveling - wave electrodes , are essential for high - speed and long - haul optical fiber transmission systems since the wavelength chirp is very small and the effect of the fiber dispersion is minimized
采用行波电极的m - z型外调制器调制速率高,波长的啁啾噪声理论上为零,几乎不受光纤色散的限制,已成为高速长距离光纤传输系统必不可少的器件。 - Especially , linbo3 optical modulators , using m - z waveguides and traveling - wave electrodes , are essential for high - speed and long - haul optical fiber transmission systems since the wavelength chirp is very small and the effect of the fiber dispersion is minimized
采用行波电极的m - z型外调制器调制速率高，波长的啁啾噪声理论上为零，几乎不受光纤色散的限制，已成为高速长距离光纤传输系统必不可少的器件。 - In high - speed direct optical modulation of laser diodes , the frequency chirp of the modulated signal cannot be eliminated . then the optical external modulators play more and more important role in large capacity optical transmission systems , and have become a subject of intense study
在高速光调制中，直接调制引起的啁啾噪声难以克服，光外调制器在大容量光纤传输系统中，扮演着越来越重要的角色，成为当前的研究热点。 - Lithium niobate ( linbo3 ) has been studied and documented extensively for over three decades because of its good electro - optic coefficient and acousto - optic coefficient , its ease of processing , and its environmental stability . it is readily available commercially and is the material of choice for external modulators in long - distance high - bit - rate systems up to l0ghz
Linbo _ 3已经被广泛的研究了三十年，由于它具有高的电光系数和声光系数，工艺简单，材料环境稳定等优点， linbo _ 3材料集成光子器件已经应用到实际光网络中，已经成为远距离高速网络系统( 10ghz以上)的外调制器优先选用的材料。
