The single-mode conditions of the SOI-based rib waveguide is first analyzed, and applied to the whispering gallery modes embedded circular octagonal resonator filter.
本文分析了SOI脊波导的单模条件,结合SOI波导模型提出了内嵌圆式正八边形谐振腔的回音壁模式滤波器。
5) Whispering-gallery mode
回音壁模式
1.
The energy distribution and quality factors of different radial-order whispering-gallery modes are calculated.
本文使用时域有限差分法研究了六种不同折射率分布的圆柱型光学微腔,计算了不同阶径向回音壁模式的能量分布和在棱镜耦合状态下的品质因数,分析了渐变型和突变型折射率分布对微腔性能的影响。
6) Whispering Gallery Mode
回音壁模式
1.
Based on the Whispering Gallery Mode, a kind of laser with intrinsic high quality factor and low threshold can be obtained, which is called microsphere laser.
利用回音壁模式微球腔的高Q谐振原理,可以获得微球激光。
2.
The main characteristics were found to be whispering gallery mode from both the near field and far field image.
结果表明InGaP微盘的近场发光图样不仅反映出荧光图象的回音壁模式特征,即沿微盘周界显示为一圈红色亮环,而且证实荧光图像中的红色亮环实际上与更精细的由分立的周期性亮点组成的近场光场分布相对应。
3.
Pumped by evanescent wave along the fiber axis,dye gain is confined in the evanescent field of whispering gallery mode (WGM) of the fiber,which leads to a low pumping threshold for lasing emission.
采用轴向隐失波激励增益的方式,使激光增益区域局限在光纤回音壁模式的模场区域内,显著地降低了回音壁模式光纤激光辐射的抽运阈值,由此形成一种低阈值的回音壁模式光纤激光器。
补充资料:回音壁
1.一种能将声音沿墙面传送的环形墙壁。因声波的波长比围墙半径小得多,声波以束状沿墙面连续反射前进,故靠墙轻声细语,在远处贴近墙面仍能听清。北京天坛南部的回音壁,建于明嘉靖九年(公元1530年),是砖砌圆形光滑的大围墙,高6米,直径65米。
