Abstract
We present an inverted structure of microaxicon, called a microaxicave, with periodic micro-conic-cave shapes, to generate circular hollow beams. A microaxicave is fabricated in a quartz substrate with the combination of direct laser writing and inductively coupled plasma etching. The hollow beam generated by the quartz microaxicave is directly recorded with a CCD camera, and the hollow beam is consistent with analysis by the diffraction theory.
