About

Hagop Djeghelian is a researcher whose work sits at the intersection of microfabrication, optical engineering, and chemical sensing. His most notable contribution is the development of a direct-dispense technique for fabricating polymeric waveguides—an automated, robotic approach that uses fugitive organic inks and cross-linkable polymers to create optical sensor arrays. This method, detailed in his highly cited 2008 paper (17 citations), represents a significant advance in direct-write microfabrication, offering a scalable and versatile platform for integrating optical chemical sensors. By enabling precise, maskless deposition of waveguide structures, Djeghelian’s work has helped bridge the gap between lab-scale prototyping and practical sensor deployment. His contributions are particularly relevant for researchers exploring low-cost, rapid-prototyping routes in photonics and environmental monitoring. Though his publication record is focused, the impact of this single, foundational paper underscores his role in advancing the toolkit for optical sensor integration.
