A new fiber-communication miniature sensor module

Abstract

Sensing using multi-chip package for optical sensing device enjoys the benefits of both optics and integrated circuits. By including the advent of MEMS technologies it can potentially lead to a new generation of miniaturized optical sensing devices and system. We propose and fabricate a miniaturized radiation-sensing module, which transfer the output analog signal to a light signal and it can be easily delivered through a single mode fiber. It consists of an infrared sensing thermopile, an ASIC chip and a LED, which acts as an electric-optical signal transfer component. Details of these components design, fabrications, experimental results are presented in this paper.
