We demonstrate that a novel family of miniaturized deformed helix ferroelectric liquid crystal cells that has recently been developed in the context of distributed optical sensing networks can also be used to realize fully monolithic, actively Q-switched waveguide lasers as well as actively mode-locked all-fiber lasers. Those cells enable the development of pulsed laser sources with the same level...
Er3+ doped single-crystalline layers are particularly interesting active media for compact waveguide lasers emitting at 1.5–1.6 μm [1]. Recently bulk monoclinic potassium double tungstates KRE(WO4)2 (RE = Y, Gd, Lu) have been shown to be excellent laser hosts for erbium ions, demonstrating efficient laser performance under direct in-band pumping into 4I13/2 energy level [2]. However, the highest doping...
In this paper the recent advances in waveguide lasers fabricated by ultrafast laser inscription (ULI) are reported with the focus on Yb:YAG waveguide based lasers in two different operation regimes. Watt level output powers in single longitudinal mode (SLM) as well as modelocked (ML) operation are demonstrated.
During the past decade, femtosecond pulse direct-laser-written (fs-DLW) waveguides in transparent materials have emerged as an enabling technology for the production of laser-active integrated photonic devices [1]. The thulium (Tm3+) ion is attractive for its eye-safe broadband emission at ∼2 μm (3F4 → 3H6 transition). Tm waveguide lasers are interesting for environmental and medical sensing applications...
Silicon nitride (Si3N4) waveguide platforms [1,2] are interesting candidates for optical interconnects and sensing applications [3] thanks to high quality passive components, transparency for NIR and visible wavelengths and their compatibility with CMOS process technology. Unfortunately, no native light sources are available for Si3N4 platforms and the integration of active materials, i.e. III-V compounds,...
