摘要：
We propose a novel asymmetric dual-core hybrid photonic crystal fiber (PCF) coupler composed of a silicon tube as the left core and a silica core as the right core. The control of picosecond pulse delay is achievable by means of power adjusting. The transmission modes, dispersion characteristics and coupling coefficients of the proposed coupler are investigated numerically. The results demonstrate that it is possible to obtain 2.0 ps time delay for soliton pulse with 2.0 ps temporal width within 1 cm length. Further numerical results show that the coupler can generate 10.0 ps undistorted time advance within 5 cm length. (c) 2013 Elsevier Ltd. All rights reserved.
