N. Mustafa et al., Terahertz bandwidth prediction for amplitude modulation response of unipolar intersubband semiconductor lasers, IEEE PHOTON, 11(5), 1999, pp. 527-529
An analysis is performed of the direct-current (dc) amplitude modulation re
sponse of unipolar intersubband: semiconductor lasers. It is shown that uni
polar lasers have the potential for achieving terahertz de modulation bandw
idths.
