     three designs of micro-optic structures have been analyzed by two-dimensional simulation. compared with traditional spherical microlenses, the micro-optic structures have the same ability to collect radiation and do not have the disadvantages of traditional microlenses. in our analysis the micro-optic structures are simple grooved notches above the space between two adjacent mesas. we also investigate the characteristics of insb focal-plane arrays with both spherical microlenses and micro-optic structures under oblique incident radiation. empirical formulas were derived to describe the response and crosstalk as a function of incident radiation angle. our results show that the micro-optic structures can be effectively used in radiation collection for insb infrared focal-plane arrays.
