The simulation shows the 3- dB-modulation bandwidth can be doubled and the chirp can be reduced by a factor of more than three. These improvements could be explained by an increase in differential net gain in coupled cavities. The result shows a possibility of high-speed and low-chirp operations of transverse coupled cavity VCSELs for higher data rates and longer link lengths of single-mode fiber transmissions  ISSN : 0021-4922  Journal Name : JAPANESE JOURNAL OF APPLIED PHYSICS  Volume : 54  Issue Number : 9  Publishing Year : 1435 AH 2015 AD  Article Type : Article  Added Date : Saturday, August 19, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email S.T Hu, Hu, S.T Investigator Doctorate   A Ahmed Ahmed, A Researcher Doctorate   F Koyama Koyama, F Researcher Doctorate koyama@pi.titech.ac.jp Files File Name Type Description  42687.pdf pdf   Back To Researches Page
