Frequency and intensity noise of a grating-tuned external-cavity quantum cascade laser
Irene La Penna, Tecla Gabbrielli, Cristina Rimoldi +6
Quantum cascade lasers (QCLs) are semiconductor-heterostructure devices known for their emission in the mid-infrared and THz spectral regions. Due to their operating regime, their…

Impact of coherent mode coupling on noise performance in elliptical aperture VCSELs for datacom
Cristina Rimoldi, Lorenzo L. Columbo, Alberto Tibaldi +4
We study the dynamical behavior of medium-size multimode VCSELs with an elliptical oxide aperture, selected for the best trade-off between high output power and modulation speed fo…
