The Institute of Microelectronics of Barcelona Centro Nacional de Microelectrónica (IMB-CNM) belongs to the Consejo Superior de Investigaciones Científicas (CSIC), the main research institution in Spain. This institute's activity in technologies, devices and integrated circuits based on the traditional Silicon Microelectronics, has evolved into a robust Si3N4/SiO2 platform for biophotonics, tele/datacom and sensing applications, from the visible to the near infrared wavelength spectrum.
