Femtosecond fiber laser direct writing of optical waveguide in glasses
There is a great deal of interests and efforts in the area of femtosecond (fs) laser direct writing of transparent materials, which shows promise to be a powerful and flexible technique for rapid fabrication of photonic micro-device, such as gratings, waveguides and optical amplifiers. Waveguide properties depend critically on the sample material properties and writing laser characteristics. In...
متن کاملDirect writing of guided wave devices inside bulk glass using femtosecond lasers
We review femtosecond laser-direct write inscription of guided wave structures in bulk glass and discuss our recent demonstrations of a range of 2and 3-D photonic devices using this technique. Figure 1: Schematic of the perpendicular writing method used to inscribe waveguides in bulk glass. The components are A: 150fs Ti:Sapphire laser, B: in-line camera, C: variable slit for beam shaping, D: 2...
متن کاملElectro-optical tunable waveguide embedded multiscan Bragg gratings in lithium niobate by direct femtosecond laser writing.
optical tunable Bragg gratings in lithium niobate fabricated by direct femtosecond laser writing. The hybrid design that consists of a circular type-II waveguide and a multiscan type-I Bragg grating exhibits low loss ordinary and extraordinary polarized guiding as well as narrowband reflections in the c-band of optical communications. High bandwidth tunability of more than a peak width and near...
متن کاملWaveguide electro-optic modulator in fused silica fabricated by femtosecond laser direct writing and thermal poling.
An integrated electro-optic waveguide modulator is demonstrated in bulk fused silica. A Mach-Zehnder interferometer waveguide structure is fabricated by direct writing with a femtosecond laser followed by thermal poling. A 20 degrees electro-optic phase shift is achieved at an operating wavelength of 1.55 microm with an applied voltage of 400 V and an interaction length of 25.6 mm, which corres...
متن کاملDirect-writing of PbS nanoparticles inside transparent porous silica monoliths using pulsed femtosecond laser irradiation
Pulsed femtosecond laser irradiation at low repetition rate, without any annealing, has been used to localize the growth of PbS nanoparticles, for the first time, inside a transparent porous silica matrix prepared by a sol-gel route. Before the irradiation, the porous silica host has been soaked within a solution containing PbS precursors. The effect of the incident laser power on the particle ...
