Effect of fabrication error on the sensitivity of a one-dimensional photonic crystal sensor for cancer detection

Ali Mohammadi, Seyed Asghar Mohammadi, Mehdi Hosseini

One-dimensional photonic crystal (1D-PC) biosensors are promising for applications like cancer detection due to their high sensitivity, but their performance is often compromised by unavoidable fabrication errors. However, theoretical analyses often do not quantitatively assess the impact of these fabrication errors on …

Analysis of Manufacturing Process Errors on the Functionality of Photonic Crystal Sensors

Vahid Fallahi, Mehdi Hosseini, Zoheir Kordrostami

In this paper, a novel study utilizing statistical simulations explores the fabrication errors (Fab-errors) associated with optical sensors based on 2D photonic crystals (PCs). The findings indicate that these Fab-errors, stemming from the arrangement of dielectric rods within the structures, adhere to …
