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 […]
Thermal Drift in On-Chip: Photonic crystal sensors (PCS) have gained significant traction in lab-on-a-chip technologies due to their high sensitivity and compact nature. However, one of the fundamental challenges in their deployment is thermal drift, a phenomenon where temperature fluctuations cause changes in the optical properties of the sensor, leading to measurement inaccuracies. This article […]
