摘要： A near infrared (NIR) semiconductor laser system is shown for gas sensing. An embodiment is centered on the use of a system with a much wider tunable laser, which today has a scan band of more than 150 nanometers (nm) to as much as 250 nm or more. In some cases the scan band is about 400 nm or more. This is achieved in the current embodiment through the use of a widely tunable microelectromechanical system (MEMS) based Fabry-Perot filter as an integral part of the laser cavity. Using this technology, these systems are capable of capturing a variety of gases in the any of the well-known spectroscopic scan bands, such as the OH, NH or CH. For example, a single laser with a 250 nm scan band window between 1550-1800 nm can capture ten or as many as twenty hydrocarbon-based gases simultaneously.

摘要： Integrated spectroscopy systems are disclosed. In some examples, integrated tunable detectors, using one or multiple Fabry-Perot tunable filters, are provided. Other examples use integrated tunable sources. The tunable source combines one or multiple diodes, such as superluminescent light emitting diodes (SLED), and a Fabry Perot tunable filter or etalon. The advantages associated with the use of the tunable etalon are that it can be small, relatively low power consumption device. For example, newer microelectrical mechanical system (MEMS) implementations of these devices make them the size of a chip. This increases their robustness and also their performance. In some examples, an isolator, amplifier, and/or reference system is further provided integrated.

摘要： To address counterfeit problems, for example, we propose a secure, flexible, and cost-effective authentication solution that can be integrated into conventional distribution logistic systems. The proposed solution for product authentication and distribution channel validation comprises three major components: 1) machine-readable Raman-active chemical taggant; 2) a taggant reader; and 3) a taggant eraser. The proposed solution is to control and validate the distribution channel by authenticating the origin of products. Authentication is accomplished by verification of distinct taggants associated with the articles, such as on its label, along with other product distribution information in optical, spatial-encoding indicia, such as a barcode. The taggant information is used to identify, validate, and distinguish the origin of the source of the articles, such as goods or products. The taggant material is thereafter rendered unreadable by modifying the taggants to make obtaining the information unfeasible, thereby controlling the taggants' lifecycle.
