Tin co-doping is used for photosensitive Er/Yb/P/Al/Si fibres. A 10 cm long 80% grating was written without hydrogenation to realise a single frequency DFB laser with an efficiency of 11%, the highest reported so far. A boron-co-doped germanosilicate ring next to the fibre core was used in the second approach to achieve 1 cm long high reflectors (>99.9%) and extremely low threshold single frequency DBR fibre lasers with 23% efficiency.
