A novel Y branch waveguide structure is presented, in which a transitional guide is embedded between an incident channel and an output branch. 为减小Y分支波导的分支损耗,提出在输入波导和两输出波导间引入锥形多模过渡波导。
Through experimentation, some planar waveguides, channel waveguides and Y-splitters in different scales are fabricated in er-doped phosphate glass substrate. 通过实验,在磷酸盐玻璃基质上制作出了不同比例的平板波导,沟道波导和Y型分路器。

The distribution of the axial velocity is in a cosine form along the direction parallel to the main channel, its amplitude of velocity decreases slowly, in the flow direction, and finally tends to smooth off. 沿y方向,轴向速度按余弦规律分布,并且随着向射流组下游发展,其速度振幅逐渐减少,直到趋于平坦。
By controlling the condition of the anodized process, the special AAO template with branched channel structures can be formed because of the unstable growth of the membrane. This may provide a new opportunity for fabricating Y-shape or T-shape nanowires and nanotubes by using the template method. 充分利用这种不稳定生长特性,通过控制AAO模板的阳极氧化条件,可得到具有分枝孔道结构的特殊模板,这为利用模板法制备各种Y形或T形纳米线、管提供了新的发展空间。
The mixing of solution in the Y-type microfluidic chip required a long channel and the mixing efficiency was not high enough, because the predominant flow type in such channel was laminar. 由于溶液在微流控芯片中主要以层流方式流动,因此Y型芯片中溶液的混合需较长的通道,且混合效率不高。
The chip was used to detect ATP, in which the length of the channel reduced from 400 mm in Y-type chip to 40 mm and the detection limit was reduced to 20 nM. 以ATP的检测为例,芯片通道的长度由Y型芯片中的400mm缩短到了40mm,检测下限降低到了20nM。
The scheme embeds the watermark information into the Y channel obtained through transformation by the original color image. 该算法将水印信息嵌入彩色载体图像提取得到的Y通道中。
It was observed that the split uniformity could be improved by using the Y-shaped channel network with the cross-section ratio of main to branch channel was 2:1, and by using an air plasma treated PDMS substrate. 采用主/支通道截面比为2:1的Y型通道构型、对PDMS通道基片用等离子体预处理,能在一定程度上提高分流的均匀性。
