Efficient Vertical-Cavity Mid-IR Thermal Radiation to Silicon-Slab Waveguide Coupling Using a Shallow Blazed Grating [PDF]
In this work we investigate the coupling of radiation originating from a vertical-cavity enhanced thermal emitter (VERTE) into an optical waveguide, which can, for instance, act as a sensing element.

Photonic Terahertz Wireless Communication Enabled by a Blazed Grating for Frequency-Selective Beam Separation [PDF]
In future 6G systems, terahertz (THz) waves are expected to be essential for enabling extremely high-capacity wireless communication. For such systems, efficient separation of multiple THz waves is required.

Wide band UV/Vis/NIR blazed-binary reflective gratings: two lithographic techniques investigation [PDF]
We report on subwavelength reflective gratings for hyperspectral applications operating in the 340 nm-1040 nm spectral range. The blazed grating period is 30 μm and is composed of 2D subwavelength binary structures with sizes in-between 120 nm and 350 nm.

Design and Study of a Reflector-Separated Light Dispersion-Compensated 3D Microscopy System [PDF]
The secondary-phase grating-based tomographic microscopy system, which is widely used in the biological and life sciences, can observe all the sample multilayer image information simultaneously because it has multifocal points.

MLgrating: a program for simulating multilayer gratings for tender X-ray applications [PDF]
Multilayer gratings are increasingly popular optical elements at X-ray beamlines, as they can provide much higher photon flux in the tender X-ray range compared with traditional single-layer coated gratings.
