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 ...

Phase gratings for plasmon focusing [PDF]
, 2005 We report gratings structures realized for the creation of focused plasmons through noncollinear phasematching. The gratings are created on gold by focused ion beam milling and the plasmons were measured using phase sensitive photon scanning tunneling ...
