Photoluminescence spectroscopy is a simple and powerful characterization technique to determine material properties dynamic effects in metal–halide perovskite optoelectronic systems. However, self-absorption thin film cavity effects, amplified due their high refractive indices, can have significant impact on spectral lineshapes, affecting the inferences drawn from such characterization. In this...

Lock-in carrierography (LIC), a recently emerging camera-based imaging technique, is proving to be very promising for noncontact and quantitative characterization of electrical/electronic properties semiconductor optoelectronic materials/devices at different stages research, fabrication, manufacturing. This tutorial devoted LIC it contains four sections. First, the background terminology, needs...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

We present a 2-port terahertz vector network analyzer (VNA) based on four continuous-wave (CW) photomixers and pair of telecom-wavelength CW lasers. The presented optoelectronic VNA is free-space coupled can operate continuously from 0.1 THz to 1 with resolution 2 MHz. demonstrate two different applications it: the determination material properties quartz wafer characterization distributed Brag...

General intelligence involves the integration of many sources information into a coherent, adaptive model world. To design and construct hardware for general intelligence, we must consider principles both neuroscience very-large-scale integration. For large neural systems capable attributes photonics communication electronics computation are complementary interdependent. Using light enables hig...

The reproducible low-cost fabrication of functional metal-polymer nanocomposites with tailored optoelectronic properties for advanced applications remains a major challenge in applied nanotechnology. To obtain full control over the nanostructural evolution at the metal-polymer interface and its impact on optoelectronic properties, we employed combined in situ time-resolved microfocus grazing in...

PURPOSE For intracytoplasmic sperm injection in the absence of sperm motility it can be virtually impossible to distinguish viable from nonviable sperm. A reliable means to identify viable nonmotile sperm is needed and would likely improve the intracytoplasmic sperm injection success rate. Optoelectronic tweezers are a new technology that uses light induced dielectrophoresis fields to distingui...

We develop light-driven optoelectronic tweezers based on the organic photoconductive material titanium oxide phthalocyanine. These tweezers function based on negative dielectrophoresis (nDEP). The dynamic manipulation of a single microparticle and cell patterning are demonstrated by using this light-driven optoelectronic DEP chip. The adaptive light patterns that drive the optoelectronic DEP on...

Welcome to the first special issue of Applied Optics on computer-aided design for optoelectronic systems. This special issue stemmed from our realization of the need for dialogue between optoelectronic system designers and computer-aided-design developers, as well as from the realization that various research groups are developing or, in some instances, have already developed and commercialized...
