1. A system for assembling an optical die to an optical substrate, the system comprising:
a gantry mechanism;
a tool attached to the gantry mechanism and including:
a mating surface for temporarily interfacing the tool to the optical die;
a retention apparatus configured to temporarily couple the optical die to the mating surface; and
a tool optical coupler positioned at the mating surface and configured to form an optical connection to the optical die when the optical die is positioned at the mating surface;
a platform disposed under the gantry mechanism and configured to retain the optical substrate;
optical test equipment operatively coupled to the tool optical coupler; and
a controller, wherein an input terminal of the controller is coupled to an output terminal of the optical test equipment.
