Numerical and experimental studies on photonic crystal waveguide directional couplers (DCs) with coupling-strength-control defects are reported here. The basic structure consists of two parallel-coupled single-defect waveguides separated by a triple-line air-hole array, with some air holes in the middle of the triple-line eliminated. Fundamental operation as the DC at a wavelength of /spl sim/1.3 /spl mu/m is observed with a short coupling length.
