“…The performance of the waveguides fabricated by ultrafast laser inscription depends on the ultrafast laser pulse (wavelength, pulse energy, pulse duration, repetition rate, and polarization) and on processing conditions (scan speed, focal depth, and irradiation geometry), as well as on the material response (substrate material properties) [3]. This technique has been successfully applied to fabricating channel waveguide devices in a wide variety of transparent materials, including glasses, crystals, ceramics, and polymers [4][5][6][7][8][9][10][11][12][13].…”

Symmetric embedded waveguides were fabricated in heavy metal oxide SF10 glass using slit-shaped infrared femtosecond laser writing in the low-repetition frequency regime. The impact of the writing parameters on the waveguide formation in the transverse writing scheme was systemically studied. Results indicate that efficient waveguides can be inscribed in a wide parameter space ranging from 500 fs to 1.5 ps pulse duration, 0.7-4.2 μJ pulse energy, and 5 μm∕s to 640 μm∕s scan speed and pointing out the robustness of the photoinscription process. The refractive index profile reconstructed from the measured near field pattern goes up to 10 −3 . In addition, propagation losses of the waveguides are tolerable, with the lowest propagation loss estimated at 0.7 dB∕cm. With a 5 μm∕s scan speed and 3.5 μJ pulse energy in a high-dose regime, few-mode guiding was achieved in the waveguide at 800 nm signal injection wavelength. This is due to a combination of increased refractive index in the core of the trace and the appearance of a depressed cladding.

“…So far, different techniques have been developed to produce optical waveguides, such as thermal ion in diffusion [1], ion implantation/irradiation [2], ion exchange [3] and femtosecond (fs) laser micromachining [4]. As a unique technique which can provide high spatial resolution in three-dimensional (3D) micro-structuring, fs-laser micromachining has been used to fabricate optical waveguides in various transparent materials, including glasses, single crystals, ceramics, and polymers [5][6][7][8][9][10][11][12][13][14][15][16][17]. By tightly focusing the fs-laser beams into the bulk of the transparent material, the refractive index modification of a small volume can be induced.…”

By using femtosecond laser micromachining, optical wave guides in both depressed cladding and dual‐line configurations have been produced in LiTaO3 crystal. The guiding properties and the thermal stability have been investigated for both geometries, which exhibit different performance. Depressed cladding waveguides support guidance along both extraordinary and ordinary index polarizations, while dual‐line waveguides support only extraordinary index polarization. Thermal annealing has been proved to be an effective method to reduce the propagation losses. For the cladding waveguide, the lowest propagation loss was as low as 0.38 dB/cm after the annealing treatment at 400 °C. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…[1][2][3][4][5] Among the various kinds of quantum structures, InAlAs/AlGaAs quantum structures have emerged as excellent candidates as active layers for the laser diodes with 808-nm-wavelength emissions. 6 The inclusion of 40% of the AlGaAs active layer in the InAlAs/AlGaAs quantum structures has inherent problems, however, due to its complicated growth process and surface oxidation.…”

InP/InGaP quantum structures with 808-nm-wavelength emissions were grown on semi-insulating GaAs (100) substrates via migration-enhanced molecular beam epitaxy. The effects of the growth conditions on the structural and optical properties of the InP/InGaP quantum structures were investigated. The scanning electron microscopy and atomic force microscopy images showed that the two-dimensional InP/InGaP quantum structures were transited to one-dimensional structures with an increasing repetition cycle. The photoluminescence spectra showed that the optical properties of the InP/InGaP quantum structures were significantly affected by various migration-enhanced epitaxy repetition numbers and growth temperatures. These results can help improve understanding of the effects of growth parameters on the structural and optical properties of InP/InGaP quantum structures for 808-nm-wavelength emissions.
