Introduction: Women make up about 19% of SPIE Optics and Photonics (one of the leading optics/photonics exhibitions and conferences) plenary speakers, representative of an overall lack of diversity in ...

High Resolution Microscopy Image quality in high-resolution optical microscopy is predominately restricted by the diffraction limit– a fundamental consequence of using lenses.  High-resolution ...

Semiconductors are essential for modern day life as we know it. From their usage in integrated circuits for computers’ logic functions to satellite communications, semiconductors allow for efficient ...

Nanowires are truly one-dimensional structures that are long in one direction and short on the lateral dimension. This dimensional reduction gives rise to interesting new phenomena such as quantized ...

Raman scattering phenomenon can be used to engineer broadband tunable lasers and to generate a broad band of frequencies in the IR spectrum. These light sources are instrumental for probing and detecting ...

Photoelectronic devices combine the vast use of electronics for processing information with the detection and the manipulation of light. Devices such as photodiodes are useful for detecting incoming light ...

Introduction to Presbyopia As we grow older the lens of the eye becomes much more rigid, hindering the ability to properly focus light onto the retina. This condition, presbyopia, affects approximately two ...

Imaging tools help us see into the world that is not possible with our naked eyes. It was with the invention of the microscope and the telescope that big frontiers in science were reached. We unlocked the ...

Introduction to the Photoacoustic Effect Alexander Graham Bell, a prolific inventor most celebrated for inventing the telephone, first observed the photoacoustic effect in 1880. Bell was experimenting with ...

Semiconductor lasers apart from silicon itself have dominated the LED industry because of their better efficiency in light emission. However, at first, most of such devices emitted light in the red to ...
