Engineered plasmon focusing on functional gratings [PDF]
, 2005 We report on the engineering of plasmon propagation and focusing by dedicated curved gratings and noncollinear phasematching. Gratings were created on gold by focused ion beam milling and plasmons were measured using phase sensitive ...

A Chirp-Managed Tunable DBR Laser Based on Novel Cascaded Gratings
IEEE Photonics Journal, 2018 In this paper, a novel tunable DBR laser based on novel cascaded gratings is proposed for chirp management in high-speed direct modulation applications. The cascaded gratings, i.e., a tilted $\pi $ phase-shift grating followed by a normal uniform Bragg ...

Chirped-grating output couplers in dielectric waveguides [PDF]
, 1977 This paper reports on the method of fabrication and first experiments of chirped (variable period) gratings in a dielectric waveguide. Such gratings, which are proposed as a new optical building block, are used in this work as focusing output ...
