The new Photline PS-LN Polarisation Rotators from Laser Components are integrated optics waveguide devices that switch the polarisation state of an input light between two linear orthogonal output states at frequencies up to 10GHz. The output light is transmitted on either the fast or slow axis of the output polarisation maintaining fibre of the component, operating then as a TE to TM converter.
This polarisation rotation provides an efficient means for high speed polarisation switching or polarisation scrambling. The PS-LN Polarisation Rotators are available at various wavelengths including 1300nm and 1550nm and for switching bandwidth from 100MHz to 10GHz.
