A deep subwavelength structured illumination microscopy scheme via tunable plasmons is proposed. The sample is placed on a semiconductor heterostructure where terahertz plasmons generated by a current-driven instability illuminate it. Full coverage of the spatial frequency regime is obtained by tuning the plasmons through adjusting gate voltage. Hence, it is possible to reconstruct an image with a resolution down to 75 nm and up to two orders of magnitude beyond the diffraction limit. Due to the linear nature of the technique, only a weak illumination signal is required, which minimizes the likelihood of sample damage and has potential applications in bioimaging.
