Abstract
A wavelength sensor based on the optical directional coupler is proposed in the paper. The finite-difference time-domain (FDTD) method is used to calculate of the light intensity propagating thorough the structure, and to find the appropriate dimensions of the structure. A particular dimension of the device has shown 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.
