Programmable Vanishing Multifunctional Optics
Physically transient optics, a form of optics that can physically disappear with precisely controlled degradation behaviors, has widespread applications including information security, drug release, and degradable implants. Here, a set of silk-based programmable vanishing, biologically functional...[ Learn more ]

Graphene-Coupled Terahertz Semiconductor Lasers for Enhanced Passive Frequency Comb Operation
Optical frequency combs, consisting of well-controlled equidistant frequency lines, have been widely used in precision spectroscopy and metrology. Terahertz combs have been realized in quantum cascade lasers (QCLs) by employing either an active mode-locking or phase seeding technique, or a disper...[ Learn more ]
