In microwave photonics (MWP) devices, the worlds of radio-frequency engineering and optoelectronics are brought together to provide an interface between the highly dissimilar media. Despite its tremendous potential, the widespread use and application of MWP is currently limited by the high-cost, bulky, complex, and power-consuming nature of its systems. Integrated microwave photonics (IMWP) have therefore [..]

Sound Processing

From an engineering perspective, there are several aspects to the relationship between optics and sound. For example, the notation of sound events (i.e., through the musical notation system) offers a graphical representation of sound in terms of quantized frequency along a quantized time axis. In other words, optical characters are used to capture sound and [..]

Nanoscale Imaging

The bulky nature of optical components has long hindered their convenient integration into our daily lives. Digital single-lens reflex (DSLR) cameras, for example, require multiple sets of bulky lenses that must be interchanged depending on the desired imaging parameters. Analogous to the miniaturization of silicon chips that has revolutionized electronic devices over the past few [..]

A material that can control excitons — bound pairs of electrons and electron holes — at room temperature could enable optoelectronic devices for commercial applications. Excitons are created when a laser is shone onto a semiconductor device. They can transport energy without transporting net electric charge. Read more
