Abstract :
The realisation of tightly bent PANDA polarisation maintaining fibre with minimal reduction of extinction ratio and throughput power is described for the miniaturisation of polarisation maintaining fibre circuits. After mechanically side-polishing the bare PANDA fibre, bend diameters as small as 1 mm have been achieved that preserve the fibre s extinction ratio ( 35 dB) with minimal loss ( 0.1 dB).
