Abstract
This paper proposes a wavelength sensor based on the optical directional coupler. The finite-difference time-domain (FDTD) is used to calculate of the light intensity propagating thorough the structure, and to find the appropriate dimensions of the structure. The structure with the size of 0.4μm×0. 4μm, and particular lengths would provide the coupling efficiency varying linearly with wavelengths. Thus, the structure could be employed as the wavelength sensor for the wavelength in a range between 1.2μm and 1.6μm. © 2005 IEEE.
