Claim 15:
16. A method comprising
fabricating multiple optoelectronic circuits on a substrate,
wherein each optoelectronic circuit comprises at least one of
an emitter circuit configured to emit an optical signal to an output waveguide, or
a receiver circuit configured to receive and process an optical signal received from an input waveguide;

fabricating multiple one or more upturned mirrors on the substrate,
wherein each upturned mirror of the multiple one or more upturned mirrors comprises a reflective layer disposed on a mirror base,
wherein forming the reflective layer comprises forming a top surface pad,
wherein at least one of
a first upturned mirror of each one or more upturned mirrors is optically coupled to the output waveguide, or
a second upturned mirror of each one or more upturned mirrors is optically coupled to the input waveguide;

wherein the first upturned mirror is configured to send upward an optical signal generated by the emitter circuit from the output waveguide,
wherein the second upturned mirror is configured to receive from upward an optical signal to the input waveguide to be received by the receiver circuit,

testing the optoelectronic circuit of the multiple optoelectronic circuits using the first and second upturned mirrors,
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 testing is performed using a tester comprising an electrical probe head configured to contact the top surface pad, and an optical probe head facing at least an upturned mirror;

fabricating a component on the substrate after testing,
wherein the component is formed on and replaces at least one of the input or output waveguide, or the first or second upturned mirror.
