Investigation of silver as passive saturable absorber

ABSTRACT - Noble metal, including gold (Au), silver (Ag) and copper (Cu) have received an attention, especially in photonics field due to its attractive optical properties. Compared with other noble metal, Ag shows a strong surface plasmon resonance (SPR) absorption in the UV region of the electromagnetic spectrum. The SPR peak of Ag is around 400 nm while Au and Cu located at 530 nm and 570 nm which is lies in visible range. This SPR peak Ag at UV spectrum are beneficial in the enhancement of the power efficiency conversion of photovoltaic cells for harvesting solar energy and convert it to electrical energy. This plasmonic resonance is highly influenced by the shape, size and concentration of Ag nanostructures. This parameter can be controlled by varying the methods of synthesis, reducing and stabilizing agent. Besides SPR, noble metal has large third-order nonlinearity especially Ag (~10 -7 esu). Third order nonlinearity is responsible for absorption properties that important for the change of light propagation through the medium. In passive fiber laser, saturable absorber (SA) is highly dependence on the third order nonlinearity due to the nonlinear absorption of SA is proportional to this nonlinearity leads for self-starting Q-switched or mode-locked laser. This talk will discuss the fabrication of silver nano particles based passive saturable absorber using three different approaches which are printed silver nano particles, Electron beam evaporation of silver and synthesis of Silver Nanoparticles using the chemical reduction method. The developed silver based saturable absorber will be residing in Erbium doped fiber laser for a pulse laser generation and the performance of the generated pulse will be discussed and compared.

Recent Progress in Step Index Optical Fibre UV Generation

ABSTRACT - We review our work in UV generation in step-index optical fibres via nonlinear optical processes and Gadolinium(Gd)-doped optical fibres. Considerations on propagation loss are first discussed, as well as the selection and limitations of UV generation and transmission in step index optical fibres. The generation of UV wavelengths via two main nonlinear processes, namely, third harmonic generation (THG) and four wave mixing (FWM) in optical microfibres are then discussed, with an emphasis on the phase matching mechanism and initial calculations for theoretical efficiency. Next, theoretical limitations of these processes due to intrinsic surface roughness in optical microfibres are presented. Finally, the use of Gd-doped silica fibres for UV generation at the 310 nm region is demonstrated.
