摘要：

We present a novel kind of hole-based photonic crystal (PhC) taper. Based on continuous tapering and lattice distortion, this structure can transmit up to 98.4% of the incident light (computed value) for a beam reduction factor of 4:1 over a length of only 5 pm into a single row (W1) 2D PhC channel waveguide. The various properties of this taper are discussed. Experimental results for tapers realised in a III-V semiconductor epitaxial structure show that an insertion efficiency of 90% into a W1 PhC waveguide can be achieved.
