Recent observations of the gravitational wave by LIGO motivates investigations for the existence of Primordial Black Holes (PBHs) as a candidate for the dark matter. We propose quasar gravitational microlensing observations in Infrared to the sub-millimeter wavelengths by sub-lunar PBHs as lenses. The advantage of observations in the longer wavelengths is that the Schwarzschild radius of the lens is of the order of the wavelength (i.e. $R_{\rm sch}\simeq \lambda$), so the wave optics features… Expand
