摘　　要：We design a series of W1 waveguide-like parallel-hetero cavities (PHCs) made from the combination of parallel-hetero perturbation (PHP) waveguides and photonic crystal waveguides and investigate their optical properties.Spectral properties are calculated numerically using the three-dimensional finite-difference time-domain method.The resonant frequencies and quality factors are obtained for each type of PHC and comparisons are made among different types of PHC,which is helpful for predicting and understanding the properties of PHC and designing PHC based high-performance cavities.The PHCs can broaden the category of cavity design and find interesting applications in integrated optical devices and solid state lasers.
