Claim 8:
9. A method of using an optical device, the method comprising:
at an underlying device, outputting light in a first spectrum as a result of absorbing input light;
at a stacked device, formed in a single semiconductor chip, coupled in an overlapping fashion to an optical output of the underlying device, the stacked device being transparent, according to a first transmission efficiency, to light in the first spectrum:
at a plurality of light emitters formed on the semiconductor chip, each of the light emitters in the plurality of light emitters outputting at least one color of light;
at a plurality of detectors formed on the semiconductor chip, each detector associated with one or more light emitters in the plurality of light emitters, detecting light emitted from the underlying device; and
wherein the light emitters in the plurality of light emitters output light dependent on light detected by an associated detector; and
at a plurality of optical filters optically coupled to an optical input of the underlying device, wherein each filter in the plurality of optical filters is aligned with a detector from among the plurality of detectors, suppressing absorption of certain wavelengths of light by the underlying device thereby affecting light detected by the detectors and thus further affecting the light output by the light emitters.
