In a photonic crystal (PC) structure, changes to the effective index of the cladding will result in a shift in the resonant frequency, which can be used to modulate an optical signal. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions. What are Optical Modulators? An optical. In this example, we will characterize the performance of a nanobeam photonic crystal (PC) electro-optic modulator using CHARGE (electrical simulation) and FDTD (optical simulation). We show that the device exhibits an ultrahigh quality factor (Q ∼ 105) and allow us to demonstrate electro-optic.
