However, the fabrication of laser resonators and patterns of crystals is still an intractable problem. Organic single crystals have been limited to fundamental property studies despite their superior photonic characteristics. In this work by Hong-Hua Fang et al.(p. 281-288), whispering-gallery mode (WGM) resonators of BP1T and BP2T crystalline materials have been fabricated through a combination method with improved lithography and dry etching. Crystalline microresonators with different geometries over a large area are top-down fabricated with submicrometer spatial resolution. WGM lasing oscillation from circular, hexagonal, pentagonal and square resonators are definitively observed. The BP1T and BP2T crystals are characterized with high refractive index, and stable lasing in aqueous solution is demonstrated besides in the air environment. It is expected that organic crystalline materials would be used for the practical applications in a variety of organic electronic and optical devices.
