Abstract Here, we explore the application of Raman spectroscopy for the assessment of plant biodiversity. Raman spectra from 11 vascular plant species commonly found in forest ecosystems, specifically angiosperms (both monocots and eudicots) and pter

Generation of sub-100 ps pulses tunable over 48 nm is demonstrated by optically gain-switching a MEMS-vertical-cavity surface-emitting laser (VCSEL). A minimum pulse width of 61 ps and a maximum, unamplified peak power of 28 mW are demonstrated. The

Abstract Despite remarkable progress in the development of halide perovskite materials and devices, their integration into nanoscale optoelectronics has been hindered by a lack of control over nanoscale patterning. Owing to their tendency to degrade

Integrated photonic systems require nanoscale on-chip light sources. Here Li et al., fabricate a silicon chip with LEDs smaller than the wavelength of light. This characteristic implies a partially coherent light emission, which allows the realizatio
