Ultrafast laser inscribed waveguides in tailored fluoride glasses: An enabling technology for mid-infrared integrated photonics devices
T Toney Fernandez, B Johnston, S Gross +6
Zirconium fluoride (ZBLAN) glass, the standard material used in fiber-based mid-infrared photonics, has been re-designed to enable the fabrication of high index-contrast low-loss w…
Single femtosecond laser pulse interaction with mica
Saurabh Awasthi, Douglas J. Little, A. Fuerbach +1
Ultrafast, femtosecond laser pulse interaction with dielectric materials has shown them to have significantly higher laser fluence threshold requirements, as compared to metals and…
Watt-level dysprosium fiber laser at 3.15 μm with 73% slope efficiency
R. I. Woodward, M. R. Majewski, G. Bharathan +3
Rare-earth-doped fiber lasers are emerging as promising high-power mid-infrared sources for the 2.6-3.0 μm and 3.3-3.8 μm regions based on erbium and holmium ions. The intermediate…
Generation of 70-fs pulses at 2.86 μm from a mid-infrared fiber laser
R. I. Woodward, D. D. Hudson, A. Fuerbach +1
We propose and demonstrate a simple route to few-optical-cycle pulse generation from a mid-infrared fiber laser through nonlinear compression of pulses from a holmium-doped fiber o…
Fabrication of high quality sub-micron Au gratings over large areas with pulsed laser interference lithography for SPR sensors
Alexander Arriola, Ainara Rodriguez, Noemi Perez +4
Metallic gratings were fabricated using high energy laser interference lithography with a frequency tripled Nd:YAG nanosecond laser. The grating structures were first recorded in a…
Low bend loss waveguides enable compact, efficient 3D photonic chips
Alexander Arriola, Simon Gross, Nemanja Jovanovic +5
We present a novel method to fabricate low bend loss femtosecond-laser written waveguides that exploits the differential thermal stabilities of laser induced refractive index modif…
Starlight Demonstration of the Dragonfly Instrument: an Integrated Photonic Pupil Remapping Interferometer for High Contrast Imaging
N. Jovanovic, P. G. Tuthill, B. Norris +13
In the two decades since the first extra-solar planet was discovered, the detection and characterization of extra-solar planets has become one of the key endeavors in all of modern…
Integrated photonic building blocks for next-generation astronomical instrumentation I: the multimode waveguide
Nemanja Jovanovic, Izabela Spaleniak, Simon Gross +5
We report on the fabrication and characterization of composite multimode waveguide structures that consist of a stack of single-mode waveguides fabricated by ultrafast laser inscri…
