提出了一种集成波导反射镜的超小箭头阵列波导光栅。在阵列波导上采用v型弯曲波导，采用集成波导椭圆镜，减小了AWG的尺寸。小的占地面积导致波导器件的低成本，并减少了由折射率波动引起的相位误差。采用二氧化硅材料制备了8通道40ghz间距的箭头型AWG，折射率差为0.75%。该箭头AWG的尺寸为1.3 / sp1倍/ 11.6 mm，是传统AWG尺寸的1/10。插入损耗和相邻串扰分别为8.31和-28.3 dB。
The ultrasmall arrowhead arrayed-waveguide grating (AWG) with integrated waveguide mirrors has been proposed. The v-shaped bend waveguides, using integrated waveguide elliptic mirrors, were applied to the arrayed waveguide to reduce the AWG size. The small footprint leads to a low-cost waveguide device and decreases the phase error resulting from refractive index fluctuations. The eight-channel 40-GHz-spacing arrowhead AWG was fabricated from silica, with a refractive index difference of 0.75%. The size of this arrowhead AWG was 1.3 /spl times/ 11.6 mm, being 1/10 of the size of the conventional one. The insertion loss and the adjacent crosstalk were 8.31 and -28.3 dB, respectively.
