Optical rectification
Did you know?
Electro-optic rectification (EOR), also referred to as optical rectification, is a non-linear optical process that consists of the generation of a quasi-DC polarization in a non-linear medium at the passage of an intense optical beam. For typical intensities, optical rectification is a second-order phenomenon which is … See more Optical rectification can be intuitively explained in terms of the symmetry properties of the non-linear medium: in the presence of a preferred internal direction, the polarization will not reverse its sign at the same time as … See more Together with carrier acceleration in semiconductors and polymers, optical rectification is one of the main mechanisms for the generation of terahertz radiation … See more • Terahertz time-domain spectroscopy See more WebAug 26, 2024 · We observe a positive correlation between optical responsivity and I ″ ( Figure 2 d) over a range of I ″ spanning almost 2 orders of magnitude, confirming the origin of the photocurrent from optical rectification set by the junction asymmetry I ″.
