The change in the absorption loss of IR-transmitting chalcogenide glass fibers in the temperature range of -90 degrees C or= 6 microm the change in loss was mainly due to multiphonon ...
Chalcogenide glasses have attracted growing interest for their potential to meet the demands of photonic applications in Mid-Wavelength InfraRed (MWIR) and Long-Wavelength (LWIR) transmission windows. In this work, we investigated photosensitivity femtosecond laser irradiation a dedicated chalcogenide glass, along with its possible micro-optics. order address SWaP problem (Size, Weight Power), ...
We have fabricated and tested, to the best of our knowledge, the first microfluidic device monolithically integrated with planar chalcogenide glass waveguides on a silicon substrate. High-quality Ge(23)Sb(7)S(70) glass films have been deposited onto oxide coated silicon wafers using thermal evaporation, and high-index-contrast channel waveguides have been defined using SF(6) plasma etching. Mic...
In this work we present data about electronic devices based on a planar structure; inert electrode/nanophase chalcogenide glass/inert electrode in close proximity with a source of silver (Ag) oriented laterally over the chalcogenide glass film. The conductivity of the devices changes with radiation and it can be measured by contacting the two inert electrodes. Spacing of the electrodes was chos...
Chalcogenide glasses are emerging as important enabling materials for low-cost infrared imaging by virtue of their transparency in the key short-wave infrared (SWIR) to long-wave infrared (LWIR) bands and the ability to be mass produced and molded into near-net shape lenses. In this paper, we introduce a new family of chalcogenide glasses, which offer visible as well as infrared transmission an...
Te-enriched chalcogenide glass Ge(15)As(25)Se(15)Te(45) (GAST) is synthesized, thermo-optically characterized and used to fabricate a one dimensional photonic crystal cavity mode that is dynamically and reversibly tuned by temperature modulation. The optical cavity mode is designed using GAST and As(2)S(3) glasses after fully determining their temperature dependence of the complex refractive in...
Simple and direct prototyping methods are ideal for large-scale delivery of cognitive photonic hardware. Here, we choose ultrafast laser writing as a fabrication technique to later demonstrate all-optical synaptic-like performance along the laser-written waveguides in chalcogenide glass. Neuronal communication protocols, such excitatory inhibitory responses, temporal summations, spike-timing-de...
Chalcogenide glass is an optical material with excellent mid-infrared and far-infrared penetration properties. The silver-doped Ge28Sb12Se60 (GSS) chalcogenide films in this paper were deposited on a substrate by the co-evaporation technique. A continuous laser different power outputs was then used to scan at constant speed, photobleaching (PB) effects observed using microscopy. results show th...
A new type of microstructured fiber for mid-infrared light is introduced. The chalcogenide glass-based microporous fiber allows extensive dispersion engineering that enables design of flattened waveguide dispersion windows and multiple zero-dispersion points - either blue-shifted or red-shifted from the bulk material zero-dispersion point - including the spectral region of CO(2) laser lines app...
Single-mode Ge28Sb12Se60 strip waveguides, fabricated with thermal evaporation and lift-off, were demonstrated at 1.03 μm. The linear and nonlinear optical properties of these waveguides were shown to be similar to bulk samples, with differences attributed to small variations in composition of ~4 atomic % or less. From z-scan measurements at 1.03 μm using circularly polarized, ~200 fs pulses at...
