Abstract
Fully integrated photonic molecules (PMs) made of pairs of polymeric disk-shaped whispering gallery mode (WGM) cavities are structured onto flexible substrates made from liquid crystal elastomer (LCE) using 3D laser printing [1] , [2] . By triggering a reversible change of the molecular order of the LCE, the inter-cavity gap of the PM and therefore its coupling strength is precisely and reversibly tuned using temperature as an external stimulus.
