折射率差 meaning in English
refractivity
Examples
- Firstly , much effort is put into the theoretic analysis and numerical algorithm research . to calculate the mode profile of soi rib waveguide with jumps in the refractive index , a new full - vectorial finite - difference method ( fdm ) based on the lagrange interpolation of the field is presented
由于soi材料中作为波导芯层的硅折射率很大，与作为包层的sio _ 2之间有很大的折射率差，这势必对模拟数值算法的精度和边界处理等方面提出了更高的要求。 - In developing the planar lightwave circuits , the coupling loss between a waveguide with a high refractive index difference and a single mode fiber is considered . a novel spot - size converter based on a y - branch structure is proposed and numerical simulation results indicate that it can reduce the coupling loss effectively with low polarization dependent loss and good fabrication tolerance
在平面波导光器件研制中，提出了高折射率差二氧化硅波导与光纤的新型低损耗连接，与现有波导单侧变窄的结构相比较，有效的降低了连接损耗，同时具有偏振相关损耗低，工艺容差性好的优点。 - The particularity of large - section rib waveguide with large refractive index difference in soi results in some special characteristics distinguished from other waveguides , which need elaborate explanation in theory . the large bent radius of the rib waveguide hinders the device performances from improving further , and confines the device to small channel number and simple functions
Soi材料上大折射率差脊形波导结构的特殊性带来了一些特殊的性质，必须从理论上深入地探讨；脊形波导大的弯曲半径在某种程度上制约了soi波导器件性能的提高，使得多通道、多功能器件的发展受到限制。 - Owing to their unique optical properties , such as low loss and large refractive index difference between silicon and silicon oxide , soi structures can not only be used to fabricate smart integrate photonic devices , but offer the ability to integrate photonic devices into the cmos integrated circuit ( ic ) process
同时，它也具备许多优越的光学特性，比如低损耗(在通信波段) 、高折射率差，这使得它不但能用来制作灵巧紧凑的光集成器件，也为利用cmos微电子工艺实现光电集成提供了一个很好的平台。
