Publikováno v: Xu, L, Chi, N, Oxenløwe, L K, Yvind, K, Mørk, J, Jeppesen, P & Hanberg, J 2003, ' Optical label encoding using electroabsorption modulators and investigation of chirp properties ', Journal of Lightwave Technology, vol. 21, no. 8, pp. 1763-1769 . https://doi.org/10.1109/JLT.2003.815504

A novel scheme of optical label encoding by wavelength conversion based on electroabsorption modulators (EAMs) is reported. Based on the experimental observations, the chirp properties of the wavelength-converted signal are discussed and a wide dynam

Bondwire array modeling for the design of hybrid high power amplifiers above C-band

Autor: Carlos Cilla, J. Hanberg, Savar Tor Jonasson

Publikováno v: 2012 Asia Pacific Microwave Conference Proceedings.

This paper presents a bondwire array model obtained using a software based on the finite elements method and validated up to 15 GHz by measurements over a purpose-build array structure. This work addresses the limits of the inductor-based bondwire mo

2.5 Gbit/s modulation of 1300 nm single-mode photonic crystal VCSELs

Autor: Magnus Hald Madsen, S. Bischoff, F. Romstad, Dan Birkedal, J. Hanberg, Michael Juhl

Publikováno v: 2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference.

Long wavelength single fundamental mode photonic crystal VCSELs have been fabricated and demonstrated to deliver 1 mW of output power up to 90/spl deg/C. 2.5 Gbit/s modulation experiments show clear and open eyes.
