At first glance, a silicon slab perforated with a regular pattern of holes might resemble an artistic experiment in nanofabrication. But when light is introduced into this holey structure, something extraordinary happens: the slab becomes a playground for photons, bending, trapping, and guiding them in ways that defy classical intuition. This is the essence of […]
An Introduction to Photonic Crystal Waveguides Photonic crystal waveguides have emerged as a transformative platform in the field of nanophotonics, offering unprecedented control over the propagation of light. These waveguides are engineered from photonic crystals—periodic dielectric structures that create photonic bandgaps, analogous to electronic bandgaps in semiconductors. The periodic modulation of refractive index in these […]
Finite Element Analysis (FEA) plays a crucial role in optimizing the integration of photonic crystal (PhC) sensors with silicon photonics. This integration is fundamental for advancing optical sensing technologies used in biomedical applications, environmental monitoring, and high-speed optical communication. Photonic crystals, with their periodic dielectric structures, exhibit unique light-manipulation properties, such as photonic bandgaps, that […]
Temperature sensors based on one-dimensional (1D) topological photonic crystals (TPCs) represent an advanced class of optical sensors with high sensitivity and robustness against external perturbations. These sensors leverage the unique properties of topological edge states in photonic bandgap structures, offering advantages in precision, stability, and resilience to defects.
