SOI Technology Lights Up the Next Wave of Photonics Solutions
Silicon has been the mainstay of micro-nanoelectronics since the late 1950s, being widely adopted for electronic devices and complementary metal oxide semiconductor (CMOS) technologies. In the early years of the semiconductor industry, germanium was the favored material for electronic applications due to its higher carrier mobility; however, innovations at Bell Labs in surface passivation by thermal oxidation processing enabled a breakthrough in silicon semiconductor technology in the second half of the 1950s.

Capasso Group’s Largest Metalens to Date Demonstrates Potential in VR
Researchers led by Federico Capasso at the Harvard John A. Paulson School of Engineering and Applied Science (SEAS) have developed a 2-mm achromatic metalens capable of focusing RGB colors without aberrations. The researchers also developed a miniaturized display for virtual reality and augmented reality applications.

Optical Coating Simultaneously Reflects, Transmits Same Wavelength
A multi-institutional team led by professor Chunlei Guo from the University of Rochester’s Institute of Optics has developed an optical coating capable of simultaneously reflecting and transmitting the same wavelength. The new class of optical coatings has been dubbed Fano Resonance Optical Coatings (FROCs). The advance could significantly improve the efficiency of devices using hybrid thermal-electric power generation as a solar energy option.

Imaging Without Limit, on Demand
A team at Columbia University has introduced a way to program a layered crystal in such a way that it is able to open doors to imaging capabilities beyond common limits, on demand. The technique exerts control over nanolight — light that is able to access the nanoscale — providing insight into the field of optical quantum information processing.
