| 英文摘要 | By considering all possible high order diffracted waves, the authors investigate the spectral response of two-dimensional gratings for quantum well infrared photodetectors (qwips). a new method is proposed that using long period gratings may improve grating quality and reduce the resulting cross talk in grating-coupled qwips. a sensitivity analysis indicates that the influence of variation of the grating constant on the coupling efficiency is less sensitive for the long period gratings than for the short ones. a large coupling efficiency has been demonstrated for long period gratings. the calculated wide grating response spectra are in good agreement with the experiment result.
