Abstract: Apparatus for use in tuning a tunable optical device to a target wavelength, the apparatus comprising: a beam splitter (205) for tapping a portion of the light emerging from the tunable optical device (105); a walk-off reflector (210) for dividing the portion of the light emerging from the beam splitter into a plurality of beams (B 1 ,B 2 ,...); a multiple etalon (215) for tailoring the light from at least two of the plurality of beams provided by the walk-off reflector; a multiple detector (220) for detecting light from the multiple etalon and the walk-off reflector, the multiple detector providing a plurality of output signals (I 1 ,I 2 ,...); and a control unit (225) for controlling the tunable optical device by providing a control signal to the tunable optical device according to the output signals provided by the multiple detector.
