optical modulation meaning in English
光调制
光学调制
Examples
- It is found that the sensor tip with a 90 conical tip has the maximum optical modulation depth
理论和实验的结果表明，顶角处于90左右的光纤尖具有最大的光调制深度。 - 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。 - In this dissertation , a boa - type waveguide optic switch with double - heterostructure gaas / gaalas has been researched . gaas - based integrated optical devices have good temperature , good anti - radiation and optical - transmission characteristics , and also have wide transparent range of wavelength . they can also be integrated on a chip with optical active devices and electronic devices , such as semiconductor laser , optical modulation , optical amplifier , pin , and so on
基于gaas材料的集成光学器件不仅具有良好的光传输特性、温度特性、抗辐射能力和其较宽的透明波长范围，还有望进一步实现芯片与光源、光调制器、光探测器和半导体光放大器等其它光电器件以及集成电路的单片集成；采用gaas gaalas双异质结材料制作的光开关可以得到较低的开关电压，而且采用gaas gaalas异质结材料的光传输损耗很小。
