Abstract:
Embodiments of the present invention provide a compound optical filter device comprising a semiconductor substrate having an optical transducer formed on the semiconductor substrate, the optical transducer responsive to light to produce a signal or responsive to a signal to emit light. An optical filter comprises a filter substrate separate and independent from the semiconductor substrate and one or more optical filter layers disposed on the filter substrate. The filter substrate is micro-transfer printed on or over the semiconductor substrate or on layers formed over the semiconductor substrate and over the optical transducer to optically filter the light to which the optical transducer is responsive or to optically filter the light emitted by the optical transducer. In further embodiments, the optical filter is an interference filter and the semiconductor substrate includes active components that can control or operate the optical transducer.
