- 摘要：
- In this paper, the mathematical model of the modified steptheory
is derived based on the platform of two-dimensional photonic crystal
structure that is infinitely long in third dimension. The mode coupling
mechanism of photonic crystal tapers is theoretically studied using the
modified step-theory. The model is verified by comparing the transmission
spectrum obtained for the input/output defect coupler where it shows a good
match of less than 5% discrepancy. The modified step-theory is applied to
different taper structures to investigate the power loss during the
transmission. The power loss at the relative position of the taper provides an
explanation as to which taper designs give the highest coupling efficiency.
