Abstract:
1. An optoelectronic apparatus, comprising: a circuit board including a cavity within the circuit board disposed between top and bottom surfaces of the circuit board; a waveguide structure embedded in the circuit board for transmitting optical signals; and a laser transmitter for generating the optical signals, the laser transmitter comprising a serializer, a laser driver, and a laser generator, wherein the serializer, the laser driver, and the laser generator are in bare chip form, and wherein the serializer, the laser driver, and the laser generator are disposed completely within the cavity and in proximity to the waveguide, wherein the waveguide is aligned with the laser transmitter for receiving the optical signals from the laser transmitter; wherein the laser transmitter has a three dimensional integrated circuit structure such that the serializer, the laser driver, and the laser generator are stacked and electronically coupled within the three-dimensional integrated circuit structure.
