The 8×8 coupler with the waveguide mirror was designed and fabricated to investigate the waveguide minor performances. It is possible to use a mirror with various surface profiles. We have developed the low aberration mirror design. We have also proposed the arrayed-waveguide grating (AWG) using the waveguide mirror. It is suitable for the integration of the spatial light modulators because the focusing line is straight. Moreover, we have developed the arrayed-waveguide grating with integrated parabolic mirrors in the slab waveguides, which can be used for the dispersion compensator.The waveguide mirror can be used for the small bend structure. We have proposed novel v-bend structure with integrated waveguide mirror, which can reduce the optical circuits drastically. In particular, the AWG using v-bend structures in the waveguide array, the size of the circuit was about one tenth of the conventional AWG size. We have fabricated the high-resolution AWGs for time-to-space conversion based optical signal processing. The AWG had 509 waveguides in the array, and the diffraction order was 51. These values correspond to the time window of about 80 ps and to the spectral window of about 3.8 THz at 1.55 μm. The very high resolution of about 8 GHz was obtained.

设计并制作了8×8波导镜耦合器，用于研究波导镜的微小性能。可以使用具有各种表面轮廓的镜子。我们开发了低像差反射镜的设计。我们还提出了采用波导镜的阵列波导光栅(AWG)。由于聚焦线是直线的，适合于空间光调制器的集成。此外，我们还研制了在平板波导中集成抛物面反射镜的阵列波导光栅，可用于色散补偿器，波导镜可用于小弯曲结构。我们提出了一种新型的集成波导镜的V型弯曲结构，可以大大减少光路。尤其是在波导阵列阵中采用v弯结构的AWG，其电路尺寸约为常规AWG尺寸的十分之一。我们制作了用于基于时空转换的光信号处理的高分辨率AWG。AWG阵列中有509个波导，衍射级为51。这些值对应于约80ps的时间窗和约3.8太赫兹的1.55μm的光谱窗，获得了约8 GHz的很高分辨率。
