Asgard/NOTT: L-band nulling interferometry at the VLTI -- III. The mid-infrared integrated optics beam combiner for NOTT

Ahmed Sanny, Lucas Labadie, Simon Gross, Kévin Barjot et autres

The NOTT visitor instrument at the VLTI will characterize hot exozodiacal dust and young Jupiter-like planets at the water snowline via L' band nulling interferometry. The beam combination will be achieved by a four-telescope integrated optics beam combiner (IOBC) that fulfills specific …

Point-by-Point Bragg grating inscription into single-polarisation all-solid photonic bandgap fibre

Ryuichiro Goto, Robert J. Williams, N. Jovanovic, G. D. Marshall et autres

We demonstrate Point-by-Point Bragg grating inscription into the core of a single-polarisation all-solid photonic bandgap fibre. Grating strength of 7.5 dB (>;80% reflectivity) was realised at 1064 nm with linearly-polarised feedback.
