    Abstract: An optoelectronic device includes a driver die including drive circuits and first bond pads on a front surface of the driver die. An emitter die is mounted on the front surface of the driver die and includes one or more vertical emitters and second bond pads connected to the vertical emitters. An encapsulation layer contains the emitter die and has an inner surface adjacent to the front surface of the driver die. Conductive vias extend through the encapsulation layer and have inner ends connected to the first bond pads and outer ends at an outer surface of the encapsulation layer. A redistribution layer is disposed over the outer surface of the encapsulation layer and includes conductive traces, each of which is connected to at least one terminal selected from a group of terminals consisting of the second bond pads and the outer ends of the conductive vias.

    Abstract: An optical device includes a first plate having a first transparent region defining an exit face of the device, and a second plate having a second transparent region defining an entrance face of the device. At least one lens is formed over at least one of the first and second transparent regions. First and second planar reflectors are spaced apart and fixed between the first and second plates in mutually-parallel orientations diagonal to the first and second plates, thereby defining an optical path through the device from the entrance face, reflecting from the first and second reflectors, through the exit face and passing through the at least one refractive surface.

    Abstract: A method for manufacturing includes forming on a surface of a metal master a pattern that defines an array of diffractive optical elements (DOEs). The pattern is replicated from the metal master onto a layer of a curable polymer that is deposited over a transparent substrate. The polymer in which the pattern has been replicated is cured, thereby setting the DOEs in the polymer. The transparent substrate is diced so as to singulate the DOEs.
