The factors affecting optical gain were studied for Er-doped BaTiO 3 thin film waveguides. Er-doped BaTiO 3 with dopant concentrations of 0.3 – 9 at.% was deposited by metal-organic chemical vapor deposition. The luminescence efficiency was maximized by optimizing the growth temperatureand erbium concentration as well as by post-deposition annealing. Achieving monolithic integration of nonreciprocal photonic devices on semiconductor substrates has been long sought by the photonics research society. One way to achieve this goal is to deposit high quality magneto-optical oxide thin films on a semiconductor substrate. In this paper, we review our recent research activity on magneto-optical oxide thin films toward the goal of monolithic.
Although the explanation is focused on the acousto-optical modulation, the concepts introduced in this section can be readily applied to other modulation techniques such as thermo- or electro-optical devices, enabling compact high-speed reconfigurable data routers which can be cascaded, arranged in matrices, or used in combination with standard.
Thin LiNbO 3 films contrary to bulk material, provide higher intensity per unit power in waveguides, and hence a stronger nonlinear optical effect and shorter interaction length. The ability to fabricate the films on various substrates extends the spectrum of their possible applications. 2.1. Pulsed Laser Deposition. PLD, namely thin film deposition by laser ablation from a target material, is a technique in use since the end of the 1980s, which proved to be effective for depositing high-quality optical films. 5 PLD has a high potential to produce complex high-quality glassy films for integrated optical applications. Its main advantages over other deposition methods are the. Nov 01, 2018 · D.O. Carvalho, M.I.
