Classification: CPC G  H | IPC G

Claim 0:
1. A photonic integrated chip, PIC, configured for alignment and attachment of a laser diode in a predetermined position in which light from the laser diode is aligned with an input of the PIC;
wherein the photonic chip comprises an asymmetric alignment arrangement for receiving and aligning the laser diode in the predetermined position,
wherein the input comprises a coupler for receiving a laser beam from the laser diode in use,
wherein the asymmetric alignment arrangement comprises a plurality of alignment keys configured to align the attachment of the laser diode in the predetermined position,
wherein at least one pair of alignment keys are asymmetric relative to one another,
wherein the pair of alignment keys are elongate and run along a direction substantially parallel to the laser beam in use, wherein the pair of alignment keys include a gap between them defining a channel through which the laser waveguide can be aligned,
wherein the clap includes a central region having a uniform profile and two sections at either end, each having a respective first irregular profile and second irregular profile, and
wherein the first irregular profile of one of the pair is juxtaposed to the second irregular profile of the other of the pair.
