Optical waveguides in crystalline dielectric materials produced by femtosecond‐laser micromachining

Year: 2013

Type: article

Abstract: Femtosecond‐laser micromachining (also known as inscription or writing) has been developed as one of the most efficient techniques for direct three‐dimensional microfabrication of transparent optical materials. In integrated photonics, by using direct writing of femtosecond/ultrafast laser pulses, optical waveguides can be produced in a wide variety of optical materials. With diverse parameters, the formed waveguides may possess different configurations. This paper focuses on crystalline dielectric materials, and is a review of the state‐of‐the‐art in the fabrication, characterization and applications of femtosecond‐laser micromachined waveguiding structures in optical crystals and ceramics. A brief outlook is presented by focusing on a few potential spotlights.
