Atmospheric emission limits observation with ground-based telescopes in the NIR. Those emission lines are very narrow in bandwidth and thus enable for filtering them with fiber Bragg gratings to utilize the light passing in-between. We present a sche

We report on what we believe are the first volume Bragg gratings written inside bulk multicomponent fluoride glasses. The gratings inscribed with tightly focused infrared (IR)-femtosecond pulses in combination with the phase-mask technique exhibit re

We present a novel approach for the inscription of nonlinearly chirped fiber Bragg gratings (N-CFBGs) using femtosecond laser pulses. This approach allows the efficient fabrication of N-CFBGs by partially tuning the average refractive index of an alr

We report on the inscription of compact and highly efficient transmission fiber gratings by means of an amplitude mask and femtosecond laser pulses at 800 nm. With the approach, gratings with strong resonances could be realized where the total length

We report on the detailed investigation of the core to cladding mode coupling in femtosecond-written long period fiber gratings (LPFG). It is shown that the excitation of higher-order cladding modes with strong selectivity and high precision is possi

We report on the selective modal control of tailored femtosecond-written long period fiber gratings (LPFG). It is shown that the excitation of higher order cladding modes is possible with strong selectivity and high precision. The coupling behavior o

Multichannel filter elements based on fiber Bragg gratings in multicore fibers (MCF) feature excellent potential for applications in astrophotonics. However, due to slight core-to-core variations of the refractive index (RI), the resonance wavelength

The ongoing increase of peak and average power of diode lasers makes the consideration of thermo-optical effects due to absorption in the optical system necessary. Otherwise, this local increase in temperature might lead to a significant reduction of

We investigate the high-power durability of fiber Bragg gratings written directly into an ytterbium-doped large mode area fiber using ultrashort laser pulses. The gratings were successfully integrated as a high reflector into an oscillator setup reac

We present efficient long period fiber gratings written with femtosecond laser pulses at 800 nm and an amplitude mask, to the best of our knowledge, for the first time. The measured transmission spectra depict strong resonances, while the total grati
