Abstract

A wavelength locker (100) for use with a tuneable laser (60) capable of selectively producing light of fixed wavelengths, said fixed wavelengths having a substantially fixed wavelength spacing; the locker for locking the wavelength of the light to one of said fixed wavelengths and comprises: an interferometer arrangement comprising splitting means (90) for splitting the laser light to pass along two optical waveguides (92, 94) and combining means (95) for combining light from the waveguides to form at least one optical output (93, 98); wherein the optical waveguides are configured to have a difference in optical path length such that the magnitude of the at least one optical output varies cyclically with wavelength and has a waveguide period which is substantially an integer multiple of said fixed wavelength spacing; and control means (97) for controlling the laser in response to the magnitude of said optical output to lock the laser to one of said selected fixed wavelengths.
