摘要：

Based on inspiration from an inverse optimization strategy and theoretical finite-difference time-domain method simulations, an ultralow loss power coupler between two different photonic crystal waveguides was designed, fabricated and characterized. The experimental results showed that the loss was less than 1 dB for transverse electric polarized light at a wavelength of 1550 nm, which is consistent with expectations from numerical modeling. High efficiency optical couplers are critical for development of integrated optical circuit functionality. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3599841]
