  Developing a chip-based super-resolution imaging technique with large
field-of-view (FOV), deep subwavelength resolution, and compatibility for both
fluorescent and non-fluorescent samples is desired for material science,
biomedicine, and life researches, etc. Previous on-chip super-resolution
methods focus on either fluorescent or non-fluorescent imaging, putting an
urgent requirement on the general imaging technique compatible with both of
them. Here, we introduce a universal super-resolution imaging method based on
tunable virtual-wavevector spatial frequency shift (TVSFS), realizing both
labeled and label-free super-resolution imaging on a single delicately
fabricated scalable photonic chip. Theoretically, with TVSFS, the diffraction
limit of a linear optical system can be overcome, and the resolution can be
improved more than three times, which is the limitation for most
super-resolution imaging based on spatial frequency engineering. Diffractive
units were fabricated on the chip's surface to provide a wavevector-variable
evanescent wave illumination and induce tunable deep SFS in the samples'
Fourier space. A resolution of {\lambda}/4.7 for the label-free sample and
{\lambda}/7.1 for the labeled sample with a large FOV could be achieved with a
CMOS-compatible process on a GaP chip. The large FOV, high-compatibility, and
high-integration TVSFS chip may advance the fields like cell engineering,
precision inspection in the industry, chemical research, etc.
