Single electron transistors (SET) were used to realize high sensitive detection of electromagnetic waves reaching single photon counting level. Far-infrared (FIR) detectors based on two photo-excitation mechanisms in two-dimensional electron gas (2DEG) were fabricated using lithographic techniques. The analysis of the photo-response spectrum suggested the occurance of resonance with maximum at 0.6mm wavelength and half-width of 0.1mm. It was found that the resonance corresponds to a characteristic frequency of the parabolic bare confinement potential.
