A low-voltage CMOS-compatible time-domain photodetector, device & front end electronics

During the last decades, the usage of silicon photodetectors, both as stand-alone sensor or integrated in arrays, grew tremendously. They are now found in almost any application and any market range, from leisure products to high-end scientific apparatuses ...

A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Serguei Okhonin, Adil Koukab, Maxim Gureev, Alexander Kvasov, Marc Pastre, Denis Sallin

Traditionally, photodiodes operate at static reverse bias, and incident light intensity is obtained from the relatively week photocurrent. In this paper, we introduce a different concept of photodiode function: the photodiode is used in a dynamic regime wh ...

Silicon-on-Insulator Technology for Bioluminescence Imaging and Application to a Switching Photodetector

Maher Kayal, Adil Koukab, Denis Sallin, Nisrina Abdo

This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a ...

Toward direct light-to-digital conversion using a pulse-driven hybrid MOS-PN photodetector

Maher Kayal, Adil Koukab, Denis Sallin

In this Letter, a direct light-to-digital converter based on an MOS-PN photodetector driven by pulsed voltage is presented. The objective is to avoid any analog-to-digital or time-to-digital conversion and, thereby, to pave the way for a new generation of ...

Hybrid MOS-PN photodiode with positive feedback for pulse-modulation imaging

Maher Kayal, Adil Koukab, Denis Sallin

A new type of CMOS compatible photodetector, exhibiting intrinsic light-to-time conversion, is proposed. Its main objective is to start the time-to-digital conversion directly at its output, thereby avoiding the cumbersome analog processing. The operation ...
