摘要：

A new method,named step simulation, is proposed to fabricate refractive 128 X 128 element Si microlens (MLS) arrays for hybrid integration with PtSi IR Focal Plane Arrays(FPAs). By the method, the focal length of rectangle-based multilevel Si MLS arrays is over 1 millimeter, much longer than typical focal length of MLS array fabricated by conventional binary optics Fresnel technique. Si MLS arrays and IR FPAs are coupled with infrared glue. The IR responsivity of the hybrid device is improved significantly.
