Abstract:
A composite wafer includes a molded wafer and a second wafer. The molded wafer includes a plurality of first components, and the second wafer includes a plurality of second components. The second wafer is combined with the molded wafer to form the composite wafer. At least one of the first components is aligned with at least one of the second components to form a multi-component element. The multi-component element is singulatable from the composite wafer.
Abstract:
Bidirectional optical multiplexing employs a high contrast grating as one or both of a beam-forming lens and a relay mirror. A bidirectional optical multiplexer includes the beam-forming lens to focus light. The light is one or both of a light beam internal to and another light beam external to the bidirectional optical multiplexer. The bidirectional optical multiplexer further includes an optical filter and the relay mirror. The optical filter is to selectively pass a portion of the internal light beam at a first wavelength and to reflect portions of the internal light beam at other wavelengths. The relay mirror is to reflect the internal light beam along a zigzag propagation path between the optical filter and the relay mirror.
