    • The invention relates to a planar lightwave circuit including a pair of opposed concave reflective diffraction gratings sharing the same focal line, which separates first and second slab waveguide regions. The ends of input and output waveguides are positioned along the focal line for launching and receiving light directed by one or both of the diffraction gratings. The invention enables light within in a certain wavelength range to be launched from an input waveguide, directed by a single diffraction grating, and output waveguides, all within a single slab waveguide region, while light within another wavelength range will be directed from one diffraction grating to another for output waveguides in a different slab waveguide region. ® KIPO & WIPO 2007
    • 本发明涉及一种平面光波电路,其包括一对共用同一焦线的相对的凹面反射衍射光栅,该光栅分离第一和第二平板波导区域。 输入和输出波导的端部沿着焦线定位,用于发射和接收由一个或两个衍射光栅引导的光。 本发明使得在一定波长范围内的光从单个衍射光栅引导的输入波导和全部在单个平板波导区域内的输出波导发射,而另一个波长范围内的光将从一个衍射光栅 到另一个用于不同平板波导区域中的输出波导。 ®KIPO&WIPO 2007
