This paper will describe recent developments in the state-of-the art for InP/InGaAs Geiger Mode focal plane arrays developed at MIT Lincoln Laboratory. Fabrication details of highly-dense arrays on a 25-micron pitch (256 x 256) will be presented, along with techniques developed to suppress crosstalk in neighboring pixels. These dense arrays are hybrized to highly efficient read-out circuits capable of simultaneous photon-counting imaging and photon time extraction for multiple user-defined regions of interest. Matching 256 x 256 microlens arrays are attached to the hybrized APD array/ROIC. Performance data and applications of the focal plane arrays will be discussed
