Detector of THz/subTHz radiation

• Spectral region: ~30-300 GHz;
• Operating temperature: T = 300 K;
• Noise equivalent power: NEP_{140 GHz} ~3-5*10^-10 W/Hz^1/2;
• Sensitive area: S ~40x40 mkm2 (without antenna) and S ~2x2 mm2 (with antenna);
• Responce time: 10^-7 s;
• Signal at detector output: 2.5 V;
• Dimensions: 50x90 mm;
• Diameter of focused  spot (D_Airy(140 GHz)): ~ 5 mm.

At the picture there is presented Detector for registration and analysis of THz and sub-THz radiation. It includes semiconductor CdxHg1-xTe (0,17<=х<=0,3) bolometer with antenna and includes in the same case two aspheric Teflon lenses which focus radiation into sensitive element of bolometer that is integrated with amplifier.
