Opt Express 16:6609-18. 2008..We have also identified the key factors that cause low-frequency roll-off in injection-locked lasers. By increasing the slave laser's DC current bias, we have achieved a record intrinsic 3-dB bandwidth of 80 GHz in VCSELs...
- Enhanced modulation bandwidth of nanocavity light emitting devicesErwin K Lau
Department of Electrical Engineering and Computer Sciences, University of California, Berkeley, California 94720, USA
Opt Express 17:7790-9. 2009..The maximum bandwidth is shown to be inversely proportional to the square root of the modal volume, with sub-wavelength cavities necessary to exceed conventional laser speeds...
