Abstract :
The operation of coupled waveguides based on lattice-modulated photonic crystals, which were fabricated by autocloning technology, has been demonstrated. Their fundamental operations as optical directional couplers at a wavelength of 1.55 μm was observed. The estimated coupling length was 330 μm, which was in good agreement with the calculated value.
