Characterisation of Ti:diffused Channel Waveguides in Sapphire
The development of Ti:difmsed channel waveguides in sapphire is demonstrated and their characteristics discussed with a view to the development of a Ti:sapphire waveguide laser. Introduction The development of a Ti:sapphire waveguide laser would have significant impact as a versatile, compact source in portable instrumentation for applications in sensing and spectroscopy. In the bulk configurat...
متن کاملWafer bonding of gallium arsenide on sapphire
Three-inch (100) gallium arsenide wafers were bonded to (1102) sapphire in a micro-cleanroom at room temperature under hydrophilic or hydrophobic surface conditions. Subsequent heating up to 500 ◦C increased the bond energy of the GaAs-on-sapphire (GOS) wafer pair close to the fracture energy of the bulk material. The bond energy was measured as a function of the temperature. Since the thermal ...
متن کاملFluorescence of Ti(3+) ions thermally diffused into sapphire.
The thermal diffusion of Ti(3+) ions into sapphire is demonstrated, and the spectroscopic characteristics of the locally doped region are presented. The spectral line shape, polarization dependence, and excited-state lifetime of indiffused Ti:sapphire are in excellent agreement with previously published data for high-quality, bulk-doped Ti:sapphire laser crystals. The observed diffusion rate at...
متن کاملDesignable buried waveguides in sapphire by proton implantation
Buried and stacked planar as well as buried single and parallel channel waveguides are fabricated in sapphire by proton implantation. Good control of the implantation parameters provides excellent confinement of the guided light in each structure. Low propagation losses are obtained in fundamental-mode, buried channel waveguides without postimplantation annealing. Choice of the implantation par...
متن کاملMicro-Raman characterization of Zn-diffused channel waveguides in Tm(3+):LiNbO(3).
In this work micro-Raman scattering experiments have been performed in LiNbO(3):Tm(3+) samples with waveguides fabricated by Zn(2+) in-diffusion. The results shown that Zn(2+) ions enter the lattice in Li(+) sites, but also in interstitial positions. This produces a compaction of the lattice close to the surface of the sample, generating the waveguide. It is shown that this region is surrounded...
