In this project it was found that Fourier ptychographic microscopy can be improved far beyond its conventional limits via waveguide-based optical systems. Extensive in silico studies showed that images obtained on highrefractive index material waveguide chips in conjunction with hyperspectral illumination light and ﬁnely designed waveguide geometries can be combined via a modiﬁed phase-retrieval algorithm to yield a resolution below 150 nm.
