  Photonic crystal cavities (PhCCs) can confine optical fields in ultra-small
volumes, enabling efficient light-matter interactions for quantum and
non-linear optics, sensing and all-optical signal processing. The inherent
nanometric tolerances of micro-fabrication platforms can induce cavity resonant
wavelength shifts two-orders of magnitude larger than cavity linewidths,
prohibiting fabrication of arrays of nominally identical devices. We address
this device variability by fabricating PhCCs as releasable pixels that can be
transferred from their native substrate to a receiver where ordered
micro-assembly can overcome the inherent fabrication variance. We demonstrate
the measurement, binning and transfer of 119 PhCCs in a single session,
producing spatially ordered arrays of PhCCs, sorted by resonant wavelength.
Furthermore, the rapid in-situ measurement of the devices enables measurements
of the PhCCs dynamic response to the print process for the first time, showing
plastic and elastic effects in the seconds to hours range.
