Based on the study of the metal-cladding waveguide on submillimeter scale, a new scheme for wavelength monitoring is proposed in this paper. The free space coupling technique is utilized to excite the ultrahigh-order mode to act as a probe, which is considered to be very sensitive to the wavelength change. It is experimentally demonstrated that a wavelength drift of 1pm is monitored.
