“…It is because the effective refractive index of the mode measured by the prism coupling system is a necessary parameter for fitting the refractive index profile of the waveguide by the RCM. [28,29] The first dip is sharp and represents the real guided mode, whose effective refractive index is 1.9464. The remaining two dips are relatively broad, indicating that they are the irradiation modes.…”

TGG crystal can be used to fabricate various magneto-optical devices, due to its optimum Faraday Effect. In this work, 400-keV He+ ions with a fluence of 6.0 × 1016 ions/cm2 were irradiated into the TGG crystal for the planar waveguide formation. The precise diamond blade dicing with the rotation speed of 20,000 rpm and the cutting velocity of 0.1 mm/s was performed on the He+-implanted TGG planar waveguide for the ridge structure. The dark-mode spectrum of the He+-implanted TGG planar waveguide was measured by the prism-coupling method, obtaining the relationship between the reflected light intensity and the effective refractive index. The refractive index profile of the planar waveguide was reconstructed by the reflectivity calculation method. The near-field light intensity distributions of the planar and ridge waveguides were recorded by the end-face coupling method. The He+-implanted and diamond blade-diced TGG crystal planar and ridge waveguides are promising candidates for integrated magneto-optical devices.

“…Previous works have shown results regarding irradiation damage on YLF crystals; for instance, Rose et al have shown that 60 Co gamma rays and high-energy protons have an irradiation effect on Nd:YLF and Nd:YAG crystals, inducing defect centers and decreasing their optical performance [14], and many others have shown an irradiation effect via gamma ray [15], electron [16], X-ray [17], and ion irradiation [18]. As a material modification technology, the properties of multiple materials can be modified by ion implantation technology [19][20][21].…”

Neodymium-doped yttrium fluoride crystal has emerged as one of the most valuable functional materials, and has thus become a research hotspot and shown promising application value in recent years. In this work, utilizing 460 keV H and 6.0 MeV C ions implantation, the damage behavior, lattice structure change, spectral, and electrical characteristics of the Nd:YLF crystal induced by electronic and nuclear energy loss were investigated, utilizing complementary characterization techniques (X-ray diffraction, hardness and elastic (Young’s) modulus, micro-Raman, absorption, fluorescence spectra, and I–V characteristic curve). Thus, the annealing effect on the waveguide properties and the surface damage of the samples was discussed. The fabricated waveguide structure shows potential application in highly sensitive optoelectronic sensors.

“…In recent years, femtosecond laser direct writing, − following the traditional ion implantation, ion exchange, and other waveguide processes, − has become an important way to fabricate waveguides. Femtosecond laser pulses are usually focused in the substrate by a short focal length lens to achieve high peak power density.…”

The symmetrical optical waveguide structures are fabricated in Er 3+ -doped aluminosilicate glass using 800 nm femtosecond laser writing in kHz repetition frequency regime. The impact of writing parameters on the waveguide preparation with a 10× microscope objective in the longitudinal writing scheme was studied in detail. The experimental results show that, under a fixed pulse energy value of 20 μJ, the waveguides can be realized with the scan speed from 20 to 160 μm/s, and with a fixed scan speed value of 160 μm/s, the waveguide can be prepared under an inscription energy range of 5−30 μJ, indicating that the waveguide can be realized in a wide range of writing parameters. The near-field mode intensity image shows that the waveguide region possesses excellent light guiding properties. Based on the refractive index profile reconstruction method, the maximum refractive index increase in the waveguide region is estimated to be about 5.5 × 10 −4 . The lowest propagation loss of the waveguide was measured to be about 1.51 dB/cm by the waveguide side scattering method. The microfluorescence spectra show that the gain characteristics of the waveguide region are well maintained after laser processing. This work shows that the fabrication of embedded optical waveguides using ultrashort pulse laser in Er 3+ -doped aluminosilicate glass has strong feasibility and great potential to create active gain devices in the field of integrated photonics and all-optical communication.
