摘要：
Apparatus for use in tuning a tunable optical device to a target wavelength, the apparatus comprising: a light source for generating light at a wavelength which is a higher order mode of the operational wavelength of the tunable device; and a wavelength detector and control unit for monitoring the wavelength of light emerging from the tunable device and controlling the tuning voltage applied to the tunable device according to the wavelength of the light emerging from the tunable device.
