Notes:
High-temperature superconducting bolometric infrared detectors offer the promise of matching the sensitivity of HgCdTe detectors, but with an extended detection range to longer wavelengths (λ(approximately-greater-than)15μm). We fabricated high-temperature superconducting bolometers using an all-epitaxial micromachining technology based upon a YBa2Cu3Ox thin film on a yttria-stabilized zirconia free-standing 50×50μm2 membrane supported on a LaAlO3 substrate. This structure has simultaneously a low thermal conductance and a low heat capacity. Using this technology, we have made array-compatible pixels for infrared camera applications with optical noise equivalent powers as low as 6.3×10−13 W/(square root of)Hz at 32 Hz. Over more than 1 octave of frequency range, these bolometers are limited by fundamental (chiefly phonon) noise sources rather than excess film noise. © 1996 American Institute of Physics.
