High-index micro-cones for focusing and concentrating light in MWIR focal plane arrays

Two types of high-index truncated micro-cones are proposed as concentrators for focusing light on pixels of mid-wave infrared (MWIR) focal plane arrays (FPAs). They can be used to miniaturise the pixels for reducing their thermal noise and, potentially, increasing the operation temperature of FPAs w...

Description
Summary:Two types of high-index truncated micro-cones are proposed as concentrators for focusing light on pixels of mid-wave infrared (MWIR) focal plane arrays (FPAs). They can be used to miniaturise the pixels for reducing their thermal noise and, potentially, increasing the operation temperature of FPAs without sacrificing their sensitivity.
