A Single-Photon Detector Implemented in a130nm CMOS Imaging Process

Edoardo Charbon, Cristiano Niclass, Marek Gersbach

We report on a new single photon avalanche diode (SPAD) fabricated in a 130nm CMOS imaging process. A novel circular structure combining shallow trench isolation (STI) and a passivation implant creates an effective guard ring against premature edge breakdo ...

Single-Photon Synchronous Detection

Edoardo Charbon, Ties Jan Henderikus Kluter, Cristiano Niclass, Claudio Favi, Frédéric Monnier

A novel imaging technique is proposed for fully digital detection of phase and intensity of light. A fully integrated camera implementing the new technique was fabricated in a 0.35μm CMOS technology. When coupled to a modulated light source, the camera can ...

A Study of the Effects of Gamma Radiation on CMOS Single-Photon Avalanche Diodes

Edoardo Charbon, Herbert Shea, Lucio Carrara, Cristiano Niclass, Marek Gersbach, Noémy Scheidegger

The paper reports on the effects of Gamma radiation to single-photon avalanche diodes (SPADs). To the best of our knowledge, this is the first study ever conducted on SPADs fabricated in CMOS technology. A typical CMOS SPAD consists of a pn junction revers ...

A new concept for a low-cost Earth sensor: Imaging oxygen airglow with arrays of single photon detectors

Edoardo Charbon, Herbert Shea, Cristiano Niclass, Renato Krpoun, Noémy Scheidegger

This paper presents a novel concept for a compact low-cost Earth sensor based on imaging atmospheric oxygen emission at 762nm using arrays of single photon avalanche diodes (SPADs). In both nighttime and daytime there is continuous emission at 762nm due to ...
