InGaAsP diode lasers with high intrinsic bandwidth

摘要

The intrinsic frequency response and the maximum modulation bandwidths of lasers with extremely large intrinsic resonance frequencies and thus with very high 3 dB modulation bandwidth potential are discussed. It is shown that in the absence of electrical parasitics. the modulation bandwidths approach 50 GHz and that the lasers, characterized by a large differential gain, are capable of achieving very high bandwidths at relatively low operating powers.
