1. A light guided pixel configured for emissions detection, comprising:
a guide layer comprising a light guide through an opaque or reflective material layer, the light guide comprising first and second opposing ends, wherein the first end is configured to receive incident light from outside the guide layer; and a light detector layer comprising a light detecting element proximal the second end of the light guide, the light detecting element configured to detect light emissions, wherein the detected light emissions received at the first end of the light guide from outside the guide layer are channeled to the second end and to the light detecting element, and wherein the light guide comprises a wavelength selective filter material for absorbing excitation light and passing light emissions based on wavelength selective properties of the wavelength selective filter material, wherein the absorbed excitation light and the passed light emissions are received from outside the first end of the light guide.
