“…It is evident from these images that the laser irradiation has caused the evolution of well-defined lines of crystallites of the dispersoid (KLN) in the glass matrix. This can be explained as a result of interference between the incident light field and the electric field of the bulk electron plasma wave generating a periodic modulation of electron plasma concentration and the structural changes in the glass [11]. Since, the wavelength of the laser used is below the absorption edge of the glass sample (Fig.…”

“…The birefringence is caused by self-aligned nanogratings that are perpendicular to the electric field vector of the inscription laser [14]. This type of index change has been observed in fused silica [15,16], multicomponent silicate [17] and fluoroaluminate glass [18] as well as in a few crystals such as TeO 2 [19] and sapphire [20]. These in volume nanogratings should not be confused with laser-induced surface nanostructures.…”

Since the discovery that tightly focused femtosecond laser pulses can induce a highly localised and permanent refractive index modification in a large number of transparent dielectrics, the technique of ultrafast laser inscription has received great attention from a wide range of applications. In particular, the capability to create three-dimensional optical waveguide circuits has opened up new opportunities for integrated photonics that would not have been possible with traditional planar fabrication techniques because it enables full access to the many degrees of freedom in a photon. This paper reviews the basic techniques and technological challenges of 3D integrated photonics fabricated using ultrafast laser inscription as well as reviews the most recent progress in the fields of astrophotonics, optical communication, quantum photonics, emulation of quantum systems, optofluidics and sensing.
