Abstract

It has already been demonstrated that cryogenics environment is beneficial to optical systems such as infrared imaging sensors or for electro-optical interconnections for superconducting devices. A Semiconductor Optical Amplifier (SOA) as a multifunctional device could be a key element for optical amplification, optical switching and optical signal processing. As of today their high noise figure and limited amplification prevent their massive adoption in optical systems. In this paper we present how the cold temperatures dramatically improve the optical gain, noise figure, modulation bandwidth and efficiency of a SOA. The paper covers a theoretical model of SOA including the temperature as a parameter and presents experimental static and dynamic results. It concludes with an outlook on future work.
