We demonstrate two mechanisms of single photon detection in the THz spectral region by using gate-voltageinduced lateral GaAs /AlGaAs quantum dots (QDs). Firstly, a QD in strong magnetic fields (B 5 3-4 T) is operated as a single electron transistor (SETs). THz-photons (1.8-1.5 THz) excite the QD vi
