Integrated photonic building blocks for next-generation astronomical instrumentation II: the multimode to single mode transition
Izabela Spaleniak, Nemanja Jovanovic, Simon Gross +3
There are numerous advantages to exploiting diffraction-limited instrumentation at astronomical observatories, which include smaller footprints, less mechanical and thermal instabi…
Multiband processing of multimode light: combining 3D photonic lanterns with waveguide Bragg gratings
Izabela Spaleniak, Simon Gross, Nemanja Jovanovic +4
The first demonstration of narrowband spectral filtering of multimode light on a 3D integrated photonic chip using photonic lanterns and waveguide Bragg gratings is reported. The p…
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…
