A method of transfer printing. The method comprising: providing a precursor photonic device, comprising a substrate and a bonding region, wherein the precursor photonic device includes one or more alignment marks located in or adjacent to the bonding region; providing a transfer die, said transfer die including one or more alignment marks; aligning the one or more alignment marks of the precursor photonic device with the one or more alignment marks of the transfer die; and bonding at least a part of the transfer die to the bonding region.

Method for III-V/silicon hybrid integration

A method of testing one or more optoelectronic devices located on respective device coupons. The device coupon(s) are present on a wafer. The method comprises: testing the or each optoelectronic device using a corresponding testing element, the testing element(s) being located on the same wafer as the device coupon(s), by either: in a first testing protocol, operating the optoelectronic device so as to produce an optical output, and detecting the light incident on the testing element from the optoelectronic device under test, or in a second testing protocol, detecting, by the optoelectronic device under test, the light received from the testing element.
