“…Nevertheless, the overall performance of this device remains insufficient with a SHG conversion efficiency of 2 9 10 À5 %/ W-cm 2 for a 1-cm-long device, which can be explained by a very low effective nonlinear coefficient of 0.0075 pm/V. 46 Improved results have been achieved in Ref. 47 with SiO 2 films using periodical electrodes.…”

“…The origin of the local erasure is believed by the authors to be because of X‐rays exposure. Nevertheless, the overall performance of this device remains insufficient with a SHG conversion efficiency of 2 × 10 −5 %/W‐cm 2 for a 1‐cm‐long device, which can be explained by a very low effective nonlinear coefficient of 0.0075 pm/V . Improved results have been achieved in Ref.…”

The objective to induce reproducible, efficient, and stable second‐order nonlinear optical properties (SONL) in an isotropic material remains a challenge in photonics. Thermal poling allows inducing SONL properties in glasses by the formation of an axial symmetry because of the implementation of a static electric field within the glassy matrix. A description of the main poling mechanisms is proposed. Depending on the glass compositions and the poling conditions, an effort is made to correlate poling mechanisms and the strength of the implemented static electric field. A review of the main technological improvements done to develop poled‐silica‐based electro‐optical modulators as well as the SONL efficiencies obtained for different glass compositions is reported and analyzed.

“…Nevertheless, the overall performance of this device remains insufficient with a very low effective nonlinear coefficient of 0.0075 pm/V. [117] Fage-Pedersen et al have obtained the best results so far with SiO2 films using periodical electrodes. A precise control of the quasi-phase-matching wavelength and bandwidth were observed thanks to a high periodic contrast of the nonlinearity with an effective  (2) of 0.13 pm/V.…”

Numerous innovations in photonics were realized on the base of nonlinear optical properties and notably in information technologies. To take advantage of nonlinear optical properties of glass, multidisciplinary research efforts were necessary combining optics, glass chemistry, material science as well as development of optical or electrical polarizations processes. This chapter addresses both fundamental aspects of the nonlinear optical responses, but also the exploitation of nonlinear optical phenomena in glassy material. It starts by a general introduction on nonlinear optical phenomena and concepts. Then, the specific cases of second and third optical responses in glasses are treated separately and described in details as a function of the corresponding optical phenomena, the different glass families and the applications.

“…These source have even been scaled to multiple indistinguishable devices across a single chip . Furthermore the nonlinearity of the amorphous χ (3) material can be enhanced using thermal poling methods to produce an effective second order nonlinearity from a third order nonlinearity . This process uses a high voltage applied across a sample while it is heated and once it cools to room temperature this electrostatic field is frozen into the material.…”

The femtosecond laser direct-writing (FLDW) of waveguide circuits in glasses has seen interest from a number of fields over the previous 20 years. It has evolved from a curiosity to a viable platform for the rapid prototyping of small scale circuits. The field of quantum information science has exploited this capability and in the process advanced the fabrication technique. In this review the technological aspects of the laser inscription method relevant to quantum information science will be discussed. A range of demonstrations which have been enabled by laser written circuits will be outlined; these include novel circuits, simulations, photon sources and detection. This places the FLDW technique among the few integrated optical platforms to have produced individually every component required for scalable quantum computation.
