We report an absorber coupled TES bolometric polarimeter, consisting of an absorptive metal grid and a Mo/Au bi-layer TES on a suspended silicon nitride membrane disk. The electromagnetic design of the polarization sensitive absorbers, the heat transport modeling of the detector, the thermal response of the TES, and the micro-fabrication processes are presented. We also report the results of laboratory tests of a single pixel prototype detector, and compare with theoretical expectations.
