| 摘 要： | 为了减小非对称X结波导混合耦合器的串音和功耗,增大实现模式分离的非对称端分支角,提出了一种改进型设计.用光束传播法结合有效折射率法模拟分析了改进后的非对称X结波导混合耦合器的串音与功耗,结果表明其串音比原来有了大幅度的减小,而且功耗也得到了改善.

| Abstract: | In order to diminish the crosstalk and power loss of asymmetric X-junction coupler and increase the angle of asymmetric area for separating mode, an improved design of asymmetric X-junction coupler is proposed. The beam propagation method and effective index method are used to simulate and analysis the crosstalk and power loss of improved asymmetric X-junction coupler. The result shows that the crosstalk of improved X-junction has been greatly diminished and the power loss has been ameliorated. |
