Quantified Reliability of Aerospace Optoelectronics

Optoelectronics: Combining chemical worlds.

A goal of molecular materials chemistry is to develop synthetic strategies for the precise placement of molecular building blocks at nano-and mesoscale levels. If the building blocks comprise both organic and inorganic moieties, the resultant hybrid composites have the advantage of combining complementary strengths from two different chemical worlds. By piecing together a judicious choice of th...

Fundamentals of Noise in Optoelectronics

Electromagnetic radiation can be described as a stream of individual photons. In solid-state detectors (e.g., photocathodes or semiconductor photosensors), each photon of sufficient energy creates one or several mobile charge carriers which can be subsequently detected with sensitive electronic circuits, possibly after charge packet multiplication employing the avalanche effect. Two types of no...

Graphene photonics and optoelectronics

611 Electrons propagating through the bidimensional structure of graphene have a linear relation between energy and momentum, and thus behave as massless Dirac fermions1–3. Consequently, graphene exhibits electronic properties for a two-dimensional (2D) gas of charged particles described by the relativistic Dirac equation, rather than the non-relativistic Schrödinger equation with an eff ective...

Automating Optoelectronics Soldering

The unprecedented growth in the telecommunications sector in the mid to late 1990’s saw a high demand in the area of optical packages and optical networks. This sudden growth in demand for optical technology in telecom and data communication applications could not be supported by the existing manufacturing infrastructure; so, to meet the growing volume needs of the industry – the electronics ma...
