Abstract

We report progress towards multimode (MM) fibre filters for suppressing the OH emission that hinders ground based observation of the early Universe. Fibre Bragg gratings (FBGs) can filter these narrow spectral lines in single-mode (SM) fibres. Implementing them in MM fibres well-matched to astronomical instruments requires transitions between the MM fibre and several SM fibres. Such hand-crafted "photonic lanterns" require many identical FBGs to be made and spliced in place. Instead we are pursuing the idea in multicore (MC) fibres. The FBG is written at once in all the SM cores. The fibre is jacketed with low-index glass and tapered to form the core and cladding of a MM fibre, giving a monolithic FBG filter with conventional MM ports. Such a device can stand alone, or be incorporated into more elaborate instruments.
