Abstract:
1. An optical device, comprising: a glass substrate; an optical die soldered to the glass substrate to form a die-on-glass assembly; first solder bumps on the glass substrate to facilitate self-alignment by surface tension of the optical die to the glass substrate; a silicon substrate soldered to the die-on-glass assembly; a recess in the silicon substrate for receiving the optical die when the silicon substrate is soldered to the die-on-glass assembly; second solder bumps on the glass substrate to facilitate self-alignment of the silicon substrate to the die-on-glass assembly such that the optical die is accurately positioned within the recess; and a micromechanical structure on the silicon substrate to permit connection of the optical device to an external component; whereby the optical device exhibits both optical transparency through the glass substrate and micromechanical structuring from the silicon substrate.
