Pixelated Laser with Tailored Emission Spectrum Photopatterned by Digital Holographic Microscopy
Azobenzene‐based surface‐relief gratings inscribed via DHM‐integrated holographic lithography enable programmable pixelated DFB laser architectures. This approach allows independent control of grating parameters across a 2D array, enabling spatially tailored emission spectra.

The paper introduces the first logic gate implementation using optical metal–oxide‐semiconductor field‐effect transistor architecture, specifically designing two‐input and three‐input AND gates based on a silicene waveguide with pulse‐shaped gates. The key innovations include: (1) pulse‐shaped gate design.

Modulated nanoporous anodic alumina structures are engineered to enhance optical biosensing performance. A comparative study between rugate filters and distributed Bragg reflectors reveals how pore modulation and porosity govern molecular diffusion and interferometric response. Distributed Bragg reflectors exhibit superior sensitivity, highlighting the

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling
