Hitherto, two distinct families of multielement detector arrays have been used for infrared (IR)
imaging system applications: linear arrays for scanning systems (first generation) and two …

We report a five-stage interband cascade laser that operates at λ= 3.75 μ m in cw mode up
to a maximum temperature of 319 K⁠. With gold electroplating, epitaxial-side-up mounting …

Surrounding a long period grating (LPG), fabricated in a standard optical fibre, with a
material with a high thermo-optic coefficient enhances the temperature sensitivity of the LPG …

Polarization control in vertical-cavity surface-emitting lasers (VCSELs) is important because
the devices in which VCSELs are used, such as magneto-optical discs or optical …

We report significant differences between the properties of buried oxides converted from
AlGaAs and AlAs layers using selective wet oxidation. Layers of Al x Ga1− x As with x≥ 0.96 …

We report on the design and characterization of an ytterbium-doped solid core photonic
bandgap fiber laser operating at 977 nm⁠. By adjusting the fiber optogeometrical …

Resonant plasmonic and metamaterial absorbers are of particular interest for applications in
a wide variety of nanotechnologies including thermophotovoltaics, photothermal therapy, hot …

We have studied the lateral oxidation of AlxGa1− xAs (x= 0.98 and 0.92) layers contained in
vertical‐cavity lasers using cross‐sectional transmission electron microscopy. We find a fine …

We observe a polarization instability in circularly symmetric vertical‐cavity surface‐emitting
lasers. A relatively long time, 3–5 ns, is required to establish a dominant polarization state …

Control of the polarization of vertical‐cavity surface‐emitting lasers (VCSELs) using a 240‐
nm‐thick amorphous silicon subwavelength transmission grating (SWTG) is demonstrated …
