Stanford researchers have developed flat, ultrathin (sub 100nm) optical elements based on high index nanostructures which can be alternatives to refractive optical elements such as gratings, lenses, and axicons.
Stanford researchers in the Vuckovic group have fabricated thin-film 4H crystal structure Silicon Carbide with excellent quantum and classical photonics properties.
Stanford Nanoscale and Quantum Photonics Lab researchers developed a passive, magnet free, integrated on-chip laser stabilization and isolation device. Lasers need a way to prevent the light they emit from reflecting into the laser and destabilizing it.
Stanford researchers have developed a damage free method for activating buried p-type or Mg-doped epitaxial layers in III-nitride devices that improves performance and can reduce device cost when used as edge termination.
Stanford researchers have patented a silicon germanium (SiGe) electroabsorption modulator that can operate well in excess of 10 Gbps and is entirely compatible with Silicon (Si) complementary metal-oxide semiconductor (CMOS) integrated circuit fabrication.
Stanford researchers have patented a fabrication process for monolithic integration of different epitaxial materials on the same substrate for improved coupling of optoelectronic devices.
Researchers in Profs. Jonathan Fan and Jim Plummer's laboratory have patented a generalized, CMOS-compatible process to fabricate single crystal metal components on amorphous insulator substrates.
Stanford researchers at the Cui Lab have designed a self-aligned hybrid metal-dielectric surface that offers unparalleled performance in applications where both a transparent contact and a photon management texture are needed.
Stanford researchers have patented a family of white light emitting perovskites with initial photoluminescence quantum efficiencies (PLQEs) of 9% and stable emission over at least three months of continuous irradiation, with third party validation studies achieving 32% PLQE.
Stanford researchers developed a device that converts microwave signals (quantum logic) to optical signals using a silicon-on-lithium-niobate photonic crystal cavity.
