Our design allows a good optical coupling efficiency between sample and detector.
The optical coupling efficiency from a plane wave to a single-mode step-index fiber optics is studied considering the exact fiber mode field distribution.
In an effort to improve the optical coupling efficiency and also to develop QWIPs with sensitivity beyond 11 μm a partnership has been established between Goddard and the Army Research Laboratory (ARL).
The optical coupling efficiencies are further analyzed by the modal expansion model (MEM), including optical field distributions in different size photosensitive element and interrelated influences with scattering matrix method based on plane-wave expansion (PWE).
