Abstract :
Novel high-performance, symmetrical metal-oxide-metal tunnel diodes (MOMTDs) in a quasiplanar configuration (US patent 4 549 194) have been successfully fabricated, and for the first time used as room-temperature detectors for the heterodyne mixing of two CO2 lasers operating on the P14 line near λ = 10.6 μm. Using these devices, we have achieved state-of-the-art NEP (noise equivalent power) in the 4 to 6 × 10-16 W/Hz range and a D* of 5 × 106 cm Hz¿/W.
