Fabrication procedures of a LC microlaser array. (a) Schematic diagram for the fabrication process of the LC microlaser array. (b) Optical microscopy image of polymeric microtemplates. (c) Plot of the height vs. the length of the microtemplates (marked as the dashed red line in (b)) by a step profiler. Scale bar: 50 μm. Three-dimensional profiles of a microtemplate filled (d) without and (e) with LC-contained ink solutions by a contourgraph. (f) Bright-field and (g) dark-field microcopy images of the LC microlaser array. Scale bar: 50 μm.
