Focused ion beam written channel waveguides in optical crystals. In this figure, focused ion beams (e. g., usually with protons or He ions) at energy of MeV offer direct writing processing of the optical crystals, constructing buried channel waveguides at certain depths. This mask‐free irradiation could be utilized to fabricate high quality waveguides with symmetric modal profiles. (Picture: F. Chen, pp. 622–640, in this issue).
