Abstract
We describe the optical characterisation of two silicon cold-electron bolometers each consisting of a small ( 32×14 μm32×14 μm ) island of degenerately doped silicon with superconducting aluminium contacts. Radiation is coupled into the silicon absorber with a twin-slot antenna designed to couple to 160-GHz radiation through a silicon lens. The first device has a highly doped silicon absorber, the second has a highly doped strained-silicon absorber. Using a novel method of cross-correlating the outputs from two parallel amplifiers, we measure noise-equivalent powers of 3.0×10−163.0×10−16 and 6.6×10−17 WHz−1/26.6×10−17 WHz−1/2 for the control and strained device, respectively, when observing radiation from a 77-K source. In the case of the strained device, the noise-equivalent power is limited by the photon noise.
