Imaging systems providing high resolution, low light images with significant dynamic range are disclosed. The improvements to photo imaging sensors providing low costs and yet higher performance sensors may be obtained an enhanced photosensor generating a single color channel image per photosensor. The single color channel image contains luminence values corresponding to light focused onto the photosensor. The plurality of photosensors are constructed using Indium gallium nitride (InGaN) nanowire structures and nanopyramid structures used in cells within an array of cells. Photosensors may be constructed as single color imaging devices as well as multi-color devices. The generation of various color channel images are controlled using metasurface filter structures as well as color filter layers setting a wavelength for absorbed light by controlling a concentration of indium gallium nitride (InGaN) within the color filter layers.
