Abstract: Photodiodes configured to convert incident photons in the short-wave infrared (SWIR) to electric current, where the photodiodes have a PbS/PbClx core/shell nanocrystal absorber layer. The PbClx shell in the PbS/PbClx nanocrystals provide native passivation in the (100) crystal facets and enable removal of native ligands and ligand exchange on the (111) crystal facets of the PbS/PbClx nanocrystals such that the photodiode exhibits reduced current densities under reverse bias and greater infrared photoresponse, providing improved device performance as compared to photodiodes having absorber layers formed from PbS core nanocrystals alone.

Abstract: Building blocks are provided for on-chip chemical sensors and other highly-compact photonic integrated circuits combining interband or quantum cascade lasers and detectors with passive waveguides and other components integrated on a III-V or silicon. A MWIR or LWIR laser source is evanescently coupled into a passive extended or resonant-cavity waveguide that provides evanescent coupling to a sample gas (or liquid) for spectroscopic chemical sensing. In the case of an ICL, the uppermost layer of this passive waveguide has a relatively high index of refraction that enables it to form the core of the waveguide, while the ambient air, consisting of the sample gas, functions as the top cladding layer. A fraction of the propagating light beam is absorbed by the sample gas if it contains a chemical species having a fingerprint absorption feature within the spectral linewidth of the laser emission.

Abstract: An apparatus includes an amplified spontaneous emission source, which in turn includes an optical fiber. The optical fiber includes a solid core and a first end. The solid core includes a silica matrix. The silica matrix includes a rare-earth element and a glass co-dopant. The rare-earth element includes dysprosium or neodymium. The glass co-dopant includes Al2O3. The apparatus further includes a laser pump diode coupled to the first end of the optical fiber. The laser pump diode and the optical fiber cooperate to generate a spontaneous spectral emission confined to the solid core. The spontaneous spectral emission includes a simultaneous plurality of spectral regions.

Abstract: Methods for obtaining a free-standing thick (>5 μm) epitaxial material layer or heterostructure stack and for transferring the thick epitaxial layer or stack to an arbitrary substrate. A thick epitaxial layer or heterostructure stack is formed on an engineered substrate, with a sacrificial layer disposed between the epitaxial layer and the engineered substrate. When the sacrificial layer is removed, the epitaxial layer becomes a thick freestanding layer that can be transferred to an arbitrary substrate, with the remaining engineered substrate being reusable for subsequent material layer growth. In an exemplary case, the material layer is a GaN layer and can be selectively bonded to an arbitrary substrate to selectively produce a Ga-polar or an N-polar GaN layer.

Abstract: A composition having a gadolinium-, samarium-, or lanthanum-substituted porous cerium oxide and copper or gold nanoparticles. The composition can be exposed to electromagnetic radiation to form reactive oxygen species in the composition to decompose organophosphonate compounds. The composition may be made by forming a mixture of a cerium salt; a gadolinium, samarium, or lanthanum salt; and an epoxide; forming gel from the mixture; and drying the gel to form an aerogel, a xerogel, or an ambigel. Copper or gold nanoparticles are added or formed at any point in the method.
