1 W Single‐Mode Large‐Area Edge‐Emitting Laser via Non‐Hermitian Spatial Mode Filtering
We demonstrate a non‐Hermitian spatial mode filtering approach for achieving high‐power single‐mode operation in large‐area edge‐emitting laser diodes. By symmetrically coupling passive filter arrays to the main lasing waveguide, higher‐order transverse modes are effectively suppressed while preserving the fundamental mode.

PIN-PMN-PT Surface Planar Waveguides Realized via He<sup>+</sup> Implantation. [PDF]
Helium‐ion implantation turns bulk PIN‐PMN‐PT relaxor ferroelectric crystals into high‐quality planar optical waveguides. The guiding surface layer retains its single crystallinity and large electro‐optic response without postimplantation annealing, whereas a buried damage layer acts as the optical barrier.

A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...
