1. A photonic integrated circuit (PIC) structure, comprising:
a substrate;
a cavity defined in the substrate, the cavity including a first shoulder at a first side of the cavity;
a first plurality of z-stop supports for an optical device, each z-stop support of the first plurality of z-stop supports on a first support portion of the first shoulder;
a first wire extending over the first side of the cavity and between at least two z-stop supports of the first plurality of z-stop supports; and
an optical device positioned on the first plurality of z-stop supports in the cavity and electrically coupled to the first wire.
