%X Through experiment,test,and analysis,we study the surface near-field effect and optical coupling efficiency of very long wavelength quantum well infrared photodetectors (QWIP).We apply finite difference time domain modeling and the modal expansion method,and we review different diffraction couplings and different processes and consider their coupling efficiency.The experiment and analysis prove that effective grating coupling can be achieved through the reasonable design of a 2D grating for very long wavelength QWIPs.
