El Grup de Recerca en Enginyeria Òptica pertany al Centre de Desenvolupament de Sensors, Instrumentació i Sistemes (CD6) de la UPC. L'activitat del Grup està dedicada tant a la recerca aplicada com de transferència de noves aplicacions basades en el disseny de dispositius òptics i fotònics. La recerca del Grup dona lloc regularment a contribucions científiques en forma de tesis doctorals, articles publicats en revistes indexades, contribucions a congressos nacionals i internacionals i patents, algunes d'elles en explotació. El fet que l'enginyeria òptica i la fotònica són tecnologies transversals que poden donar un alt valor afegit a les aplicacions industrials han fet que les activitats de transferència de coneixement experimentin un fort creixement. El Grup ha estat molt actiu en la creació d'empreses derivades (spin-offs) basades en tecnologia (set en total). Aquestes empreses contribueixen al creixement i la internacionalització de les activitats del Grup.
