Post processing of photonic crystal fibres with a CO/sub 2/ laser is a very powerful and versatile method for fabricating miniature compact fibre devices including structural long period gratings and rocking filters. A compact Mach-Zehnder interferometer was made from two consecutive structural rocking filters in a highly birefringent photonic crystal fibre. Each rocking filter had 6 complete twist periods of 0.6 mm giving a total length of just 3.6 mm. For a separation distance between the two rocking filters of 125 mm, the fringe separation (bright-dark) of the interferometer is 2.5 nm. The polarization couplers (rocking filters) are highly compact and they are expected to be temperature stable.
