Up-Conversion of Triple-Band OFDM UWB Signals by a Multimode VCSEL
2009
We present novel experimental results for the all-optical up-conversion of the triple-band orthogonal frequency-division-multiplexing ultra-wideband radio signals from lower frequency band group 1 up to higher frequency band groups 2 or 3 based on the vertical-cavity surface-emitting laser optical second- and third-order nonlinearities. Low conversion losses and error vector magnitude values, respectively, for low bias currents have been demonstrated.
