“…From the complex mechanism of effects produced by ion implantation in optical materials, here, only the main contributors to the refractive index change are considered. Refractive index change is induced by the modification of the substrate density, polarizability or structure produced by radiation damage or stoichiometric changes [9][10][11]. An approach to analyse the refractive index change, Δn, of an ion-implanted waveguide is given by…”

“…where Δn R is mainly due to the difference in polarizability before and after ion implantation which can be calculated using a basic model that relates refractive index as a function of chemical composition [9]. Refractive index change's contribution from volume change of the matrix surface caused by the induced compaction process, Δn V , can be estimated across the surface implanted through AFM measurements [28].…”

“…Interface-waveguide transmittance (t f Àw ¼ 1 À η R ), where η R is the Fresnel reflection fibre guide, the mode-size mismatch between the fibre and the waveguide (η 0 ), interface transmittance (t out ) and microscope transmittance (t m ) are needed to be accounted in order to describe the overall throughput T, given by Eq. (8) [9].…”

“…Single ion implantation has been used as a rule to produce optical waveguides, but there is a lack of control of optical confinement that limits its potential as optical waveguides [9]. However, optical waveguides can be improved by widening the barrier or directly generating the waveguide core through multiple energy ion implantations [10,11].…”

In this chapter, we present information about the design, fabrication and characterization of optical waveguides obtained by using a protocol of multiple energy ion implantations. This protocol must provide an approach to produce optical waveguides with adequate features, such as dimensions, evanescent field and optical confinement. In general, optical waveguides can be improved by widening the optical barrier or waveguide core through multiple energy ion implantations. Design of optical waveguides must consider effects induced by the ion implantation process, such as modification of substrate density, polarizability and structure. Information will be presented about optical waveguides formed mainly in laser crystals (i.e., Nd:YAG, Nd:YVO 4 ) using light ions such as H and He+ and heavy ions such as C 2 +. In general, these ions decrease the refractive index in the implanted area, producing a barrier that permits guiding in the region near the surface. Furthermore, information about nonlinear optical properties of channel waveguides containing metallic nanoparticles is presented. Composite materials containing metallic nanoparticles embedded in a dielectric matrix such as silica possess interesting properties due to surface plasmon resonance absorption features and the enhancement of the third-order nonlinear optical response. Therefore, nonlinear optical properties in composite waveguides can be used in all-optical switching devices.

“…For example, with the unique surface plasmon resonance (SPR) absorption, they can be extensively exploited to optical sensors, elaborate molecule detectors, and biomedicines [2][3][4]. Large third-order nonlinear susceptibility and optical response times in picoseconds range also make them excellent candidates for using in optoelectronics, nonlinear waveguide devices, and magnetic information storage [5][6][7]. One of the most promising techniques to fabricate the glass-based nanocomposites containing metal NPs is ion implantation, which allows the realization of high metal-filling factor and the control of depth distribution of NPs in the substrate to a certain degree [8][9][10].…”

Amorphous SiO 2 samples were sequentially implanted with Ti and Cu ions and were then subjected to thermal annealing at different temperatures. The structures and optical properties of the synthesized nanoparticles (NPs) have been characterized in detail. Our results clearly show that the pre-implantation of Ti ions into SiO 2 could strongly affect the nucleation and thermal growth of Cu NPs. Core-shell NPs consisting of Cu cores surrounded by Ti-related shells have been revealed in silica sequentially implanted with Ti and Cu ions at the same fluence of 5×10 16 cm −2 followed by 800°C annealing. The synthesized NPs exhibit significantly enhanced surface plasmon resonance (SPR) absorption and improved third-order nonlinear susceptibility as compared with those in the Cu singly implanted sample. The possible mechanisms responsible for the above results have been discussed.

The zero‐dimensional metallic nanoparticles (NPs) have attracted tremendous attention in various areas owing to the collective oscillation of electron gas that couples with electromagnetic field, known as localized surface plasmon resonance (LSPR). In practical applications, the tailoring of LSPR effect is of significant importance for promising photonic devices with designed nanocomposite systems and enhanced optical properties. Ion beam technology has been demonstrated to be an efficient method to fabricate NPs embedded in dielectrics for LSPR tailoring and material modification. By manipulating the parameters of ion beams, the shape, size, and structure of NPs can be well controlled, which enables the dielectrics to possess novel linear and nonlinear optical properties. In this review, the latest research progress on the ion beam synthesis of various NPs is systematically summarized. The tailoring of linear and nonlinear optical properties of dielectrics by NPs is discussed in detail. Selected applications are presented to indicate the development of the plasmonic NPs in dielectric systems for photonic applications.
