Introdution

Politecnico di Milano (POLIMI) is a public scientific-technological university which trains engineers, architects and industrial designers. The University has always focused on the quality and innovation of its teaching and research, developing a fruitful relationship with business and productive world by means of experimental research and technological transfer. POLIMI is one of the largest universities in Italy and it is well acknowledged in Europe as among the best technical schools for engineering. According to the QS World University Rankings, POLIMI is the 15 top Engineering Schools in the world and at the first place among all Italian universities in six scientific areas including Computer Science & Information Systems, where the Dipartimento di Elettronica, Informazione e Bioingegneria (DEIB) is specifically active and renowned. POLIMI has a leading experience in research projects and holds more than 2500 patents and has 93 accredited spin-off companies.

Role/Contribution

POLIMI will firstly develop single-photon detectors based on InGaAs/InP SPADs to be hybridly integrated in photonic integrated circuits operating at 1550 nm. Then, POLIMI will design InGaAs/InP SPADs to be heterogeneously integrated in photonic integrated circuits. A read-out integrated circuit (ROIC) will be developed for driving the SPAD and reading out the output pulses corresponding to the single photons.

Why is this project important?

For the first time, QPIC1550 will integrate single-photon detectors (InGaAs/InP SPAD) with 1550 nm photonic integrated circuits operating at temperatures easily achievable with just thermoelectric coolers, as opposed to other approaches based on superconductive detectors. This new platform will pave the way towards integrated solutions for quantum applications, thus bringing the SPAD detectors developed by POLIMI in many future products.
