摘　　要：利用光束传播法模拟了光波在不同结构的双芯光子晶体光纤内的传输状况,并计算了其耦合长度。分析了耦合长度随光波长、孔半径变化的一般规律;当双芯光子晶体光纤的结构一定时,耦合长度随波长增大而减小;孔间距和波长不变时,耦合长度随空气孔半径增大而增大。The coupling-length of the twin-core photonic crystal fiber of different structure was investigated with beam propagation method.The variation rules of coupling-length with both wavelength and air holes have been found:for a given twin-core photonic fiber,coupling-length decreases with increasing wavelength;if both hole spacing (center to center distance between the holes) and wavelength kept unchanged,coupling-length increases with the enlargement of the radius of air holes.
