“…the optimum electronic and optical properties of the semiconductor substrate, together with the low propagation loss or high gain per unit length for passive and active components formed on the overlying glass thin films. PLD is the only technique available at present for well controlled and nearly stoichiometric transfer of a multicomponent glass from a target to substrate to form high quality thin films at relatively low temperatures [13]. Soft glasses, in particular tellurite based glasses are well known for their high optical nonlinearity, low phonon energy, high rare earth solubility hosts, excellent mid-IR transparency up to ∼ 5 µm and high Raman gain, which find applications in supercontinuum generation, upconversion based visible sources, mid-IR laser sources and Raman amplifiers [14][15][16][17][18][19][20].…”

Integration of glass thin films with semiconductors promises new opportunities for novel photonic and optoelectronic devices due to the contribution of several synergetic properties. In this paper, we report the demonstration of the integration of Er 3+ -ion doped phosphate modified tellurite (PT) glass thin film waveguides with III-V semiconductor substrates. The thin films were deposited using the technique of pulsed laser deposition (PLD) and exhibit a refractive index which is very close to that of the bulk glass target used in the deposition process. Optical confinement and propagation loss measurements for the thin films deposited on GaAs substrates, with different thicknesses of silica buffer layers, is presented and shows good agreement with finite element models. Channel waveguide patterning was carried out using ultra-fast laser micromachining, and a range of optical characterization measurements are reported on confirming the high quality of the glass thin films and waveguides formed on silica and GaAs with silica buffer layers.

Fabrication and characterization of planar and channel waveguiding thin films with the goal to develop active and passive elements are intensively studied over the last 20 years. Large scale of materials and properties were tested (morphology, crystallinity, luminescence, waveguiding, etc.). The goal of our contribution is to give an overview of materials and fabrication processes which were used for development and construction of functional planar waveguide lasers (PWL). The compact survey of finalized PWL and their basic parameters is given. A special part is devoted to fabrication of waveguide lasers using laser technology. Applications of thin film waveguide lasers are mentioned.
