Claim 0:
1. A method comprising
forming a sacrificial upturned mirror,
wherein the sacrificial upturned mirror comprises a reflective layer disposed on a mirror base on a substrate,
wherein forming the reflective layer comprises forming a top surface pad,
wherein the mirror base comprises a mirror profile configured to reflect an optical signal from a waveguide or to the waveguide,
wherein the waveguide is fabricated on a surface of the substrate
wherein the optical signal is configured to reflected upward out of the surface of the substrate from the waveguide or to reflected to the waveguide from above the substrate,
wherein the waveguide is coupled to an optoelectronic circuit,
wherein the optoelectronic circuit is configured to emit an optical signal to the waveguide to the sacrificial upturned mirror, or to receive and process an optical signal received from the input waveguide coming from the sacrificial upturned mirror,

wherein the sacrificial upturned mirror is configured for testing the optoelectronic circuit,
wherein the testing is performed using a tester comprising an electrical probe head configured to contact the top surface pad, and an optical probe head facing the sacrificial upturned mirror,
wherein the sacrificial upturned mirror is configured to be removed in a subsequent fabrication step after the testing step.
