光传输损耗 meaning in Chinese
optical transmission loss
Examples
- Because the cross - section of the oversized rib waveguide we fabricated by wet - etching was trapeziform , we analyzed the transmission of oversized rib waveguide by combining effective refractive - index method . the influence of some factors on the optical transmission loss , such as material structure , the height of rib waveguide , and the thickness and refractive index of waveguide layer and up - layer of polymer material , was analyzed
因为湿法腐蚀工艺制作的反脊波导横截面是梯形状的，因此论文中采用了一种简单有效的方法，即有效折射率法，对梯形反脊波导的光传输损耗特性进行了分析，同时考虑金属电极产生热场对脊波导传播特性的影响。 - 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。
