Abstract

In the frame of the SPICA mission, new semiconductor bolometers have been designed for the POL instrument which is directly part of the HERSCHEL/PACS legacy. These detectors are cooled down to 50 mK and are sensitive to polarization for the 100, 200 and 350 μm wavelength bands. In this paper, 3D simulations have been carried out with the COMSOL Multiphysics software to design the two suspended interlaced silicon spirals which support the orthogonal absorbers (sensitive to the two polarizations) of the POL detectors. These simulations allow to optimize the design of the absorbers and to quantify the cross-polarization. In the last part of this paper, we explain how it is possible to reach the 200 and 350 μm bands from the layout of the 100-μm detector.
