A solar energy collector includes a planar waveguide formed of multiple material layers having at least two different dielectric constants. Two or more dichroic filters disposed within the waveguide core, and two or more minors are also disposed within the waveguide core. At least one optical to electrical detector positioned in alignment with each of the dichroic filters, and at least one optical to electrical detector is aligned with each of the mirrors. The dichroic filter may be formed from a plurality of material layers.
