Detectors with Interaction of Electromagnetic Radiation

The detection process of this type of photodetectors is based on direct interaction of electromagnetic radiation with electromagnetic radiation (e.g., frequency beating, etc.). Table 1.5 shows some basic types of such devices sorted according to the interaction mechanism. 

Optical parametric converter Optical equivalent of heterod3me effect the mixing of a coherent signal and a beam from a local oscillator takes place in a nonlinear optical crystal and results in foequency difference (downconversion) or their sum (upconversion) 

MOM diode Metal-metal oxide-metal electrons tunnel through a thin (of the order of angstroms) oxide layer and IR radiation generates voltage. Extremely fast (100 GHz) and uncooled 

Josephson detector Photoeffect on Cooper pairs in semiconductor within a Josephson junction 

Intrinsic Photoexcitation increases the number of free carriers by interband transitions
