Glasses for Photonic Applications




Recent advances in the application of glassy materials in planar and fiber-based photonic structures have led to novel devices and components that go beyond the original thinking of the use of glass in the 1960s, when glass fibers were developed for low-loss, optical communication applications. Exploitation of the material's compositional flexibility, combined with the ability to tailor all aspects of its size, shape, and physical properties as well as its behavior when exposed to all forms of electromagnetic radiation, has led to numerous breakthroughs. Thus, for the purposes of this review, we have divided the discussion to highlight issues of material composition and form and how both impact device function, focusing on the advances made within the past decades.
