摘要	A surface relief reflection diffraction grating is used as a wavelength compensating element for a diffraction grating coupler. The changes in wavelength are compensated for by adjusting the parameters of the reflection diffraction grating so that the dispersion of the reflection diffraction grating is generally equal and opposite to the dispersion of the diffraction grating coupler. The technique has been shown to permit the range of wavelengths which can coupled with the diffraction grating coupler to be extended from 0.7 nm to 17 nm. The lateral shift has an important contribution and can be limiting factor in wavelength compensation.
其他摘要	表面起伏反射衍射光栅用作衍射光栅耦合器的波长补偿元件。通过调整反射衍射光栅的参数来补偿波长的变化，使得反射衍射光栅的色散大致等于并且与衍射光栅耦合器的色散相反。已经证明该技术允许可以与衍射光栅耦合器耦合的波长范围从0.7nm延伸到17nm。横向偏移具有重要的作用，并且可以是波长补偿的限制因素。
