This document analyzes the characteristics of 1-D photonic crystals with a 2-layer unit cell, with one layer being silicon carbide. Transfer matrix modeling is used to calculate transmission coefficients for different material combinations. Key findings include: - Silicon/silica photonic crystals have a stop band of 850nm and pass band of 700nm, with a center gap of 1680nm. - Increasing the number of silicon carbide/silicon unit cells from 10 to 30 produces an actual stop band, with a width of 320nm. - Silicon carbide/air crystals have the widest stop band of 950nm and a center gap of 1680nm. - Small refractive
