Abstract
We present a new method for modeling and design of photonic crystal nano-beam resonators (PCNBRs) based
on cascaded transmission lines. The proposed model provides an accurate estimate of the PCNBRs properties such as
resonance wavelength and quality factor
$(Q)$
with much smaller
computation cost as compared to the brute-force numerical methods. Furthermore, we have developed a straightforward
technique for the design of high-
$Q$
PCNBRs based on resonance
modes with Gaussian electromagnetic field profiles. The results obtained by using the proposed transmission line model
are compared against numerical and experimental results and the accuracy of the model is verified. The proposed model
provides an insight to silicon cavity design and significantly reduces computational burden.
