Lightweight Integrated Optical Sensor for Atmospheric Measurements on Mobile Platforms

Understanding the role of atmospheric CO2 on the carbon cycle and climate change is needed in order to develop better models and policies for dealing with fossil fuel emissions. Compact, lightweight, low-cost sensors capable of unattended operation on remote platforms over a range of ambient temperatures and pressures will enable more efficient data collection and thorough assessment of ambient concentrations. The overall objective of the combined Phase I and Phase II projects is the creation of a compact sensor platform technology suitable for deployment from ballonsondes or similar platforms. Physical Sciences Inc. (PSI) and the group of Prof. Connie Chang-Hasnain at the University of California Berkeley propose to develop a sensor based on integration of novel integrated optical waveguides with efficient optoelectronic components on a monolithic semiconductor structure. Commercial Applications and Other Benefits: The sensor technology developed during the proposed program will have widespread commercial application. Industrial process monitoring, pharmaceutical manufacturing, law enforcement, and pollution monitoring are just some of the areas where a compact gas sensor will be valuable. Commercialization of a family of products based on the platform developed in this program will allow individuals and businesses to easily detect chemicals of interest at low cost to improve the quality of life.
