Overcoming the Abbe diffraction limit in THz spectroscopy and imaging of soft biological tissues

In this work, we consider several novel modalities of THz imaging, which overcome the Abbe diffraction limit and hold strong potential in THz biophotonics. Among them: the THz solid immersion microscopy, the THz imaging relying on photonic jets and photonic hooks, and the THz scanning-probe near-field microscopy based on a flexible sapphire fiber.
