Scalable switched slab coupler based optical phased array on silicon nitride
Pascual Muñoz, Daniel Pastor, Luis A. Bru +4
A two-dimensional optical-phased array is demonstrated by using a multiple-input star coupler, compatible with FMCW LiDAR. Previous approach using a single-input design achieves tw…
A Monolithic Integrated Microwave Photonics Filter
Javier S. Fandiño, Pascual Muñoz, David Doménech +1
Meeting the ever increasing demand for transmission capacity in wireless networks will require evolving towards higher regions in the radiofrequency spectrum, reducing cell sizes a…
A quantum entropy source on an InP photonic integrated circuit for random number generation
Carlos Abellan, Waldimar Amaya, David Domenech +5
Random number generators are essential to ensure performance in information technologies, including cryptography, stochastic simulations and massive data processing. The quality of…
