A new fiber-communication miniature sensor module

Sensing using a multi-chip package for the 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 systems. We propose and fabricate a miniaturized radiation-sensing module, which transfers the output analog signal to a light signal, which 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 electro-optical signal transfer component. Details of component design, fabrication, and experimental results are presented.
