Applications of Fiber Lasers for the Development of Compact Photonic Devices

Abstract: Ultrafast fiber lasers, with their distinct features of high stability, superior beam quality, compactness and power scalability have revolutionized a variety of applications, ranging from micromachining and medical diagnostics to basic research. One of the applications include Ultrafast Laser Inscription, a technology that has considerably improved and diversified with advances in stable, high power Ytterbium-doped fiber lasers. This paper explores the highly interdisciplinary application realm of Ultrafast L… Show more

“…The multi-scan technique was used so that waveguide width (extent in the x direction as defined in Fig. 1) could be controlled in a deterministic manner that is decoupled from changes in the waveguide height [17]. This allowed for the fabrication of arrays of waveguides with different core sizes.…”

“…The substrate translation was perpendicular to the laser beam direction. The cross section of the inscribed waveguides forming the directional couplers was controlled using the well-known multiscan waveguide shaping technique [13,14], yielding waveguides with rectangular crosssections. For each of the couplers, 10 scans with a scan-to-scan separation of 0.36 μm were used.…”

“…The technique involves irradiation of a focused femtosecond laser pulse in to a bulk material, which changes the physical properties of the material through non-linear absorption of the laser energy. This allows the fabrication of three dimensional microstructures and waveguides within the substrate 11 . The device fabrication involves two steps; a) direct writing of the desired channel pattern and waveguide structures by focused femtosecond laser pulses and b) selective etching of the modified region in hydrofluoric acid (HF) solution to produce microfluidic channels.…”
