Abstract
A device is provided for measuring radiant energy, the device comprising a substrate; a bolometer formed from a high T.sub.c superconducting material disposed on the substrate in an area that is about 1.times.5 .mu.m.sup.2 and about 0.02 .mu.m in depth; and a planar antenna disposed on the substrate and coupled to receive radiation and to impart the received radiation to the bolometer.

A device for receiving radiation, comprising:
- a substrate;
- a bolometer formed from a high T.sub.c superconducting material disposed in an area that is about 1.times.5 um.sup.2 and about 0.02 um in depth on said substrate;
- wherein said (bolometer) material has planar dimensions sized relative to dimensions of said substrate such that thermal conductance between said substrate and said (bolometer) material is determined substantially by spreading resistance between said (bolometer) material and said substrate;
- wherein said (bolometer) high T.sub.c superconducting material has planar dimensions that are less than one wavelength of the measured radiation;
- a planar antenna disposed on said substrate and coupled to impart the measured radiation to said bolometer;
- and
- a lens secured to said substrate;
- wherein said lens focuses the measured radiation onto said antenna.
