Bridging mid and near infrared by combining optomechanics and self mixing
Tecla Gabbrielli, Chenghong Zhang, Francesco Cappelli +8
This work describes a self-mixing-assisted optomechanical platform for transferring information between near- and mid-infrared radiation. In particular, the self-mixing signal of a…
Sub-doppler trace-gas photoacoustic spectroscopy
Jacopo Pelini, Stefano Dello Russo, Chenghong Zhang +10
Molecules are emerging as new benchmark for metrology and fundamental physics research, driving the demand for spectroscopic techniques combining high sensitivity and resolution. P…
Electron-to-photon noise transfer in mid-infrared semiconductor lasers
Irene La Penna, Tecla Gabbrielli, Borislav Hinkov +8
Noise characteristics of state-of-the art light sources are crucial parameters in understanding their limitations towards quantum applications. This work describes a method to stud…
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…
Shot-noise-limited emission from interband and quantum cascade lasers
Tecla Gabbrielli, Jacopo Pelini, Georg Marschick +12
The intensity noise of a laser source represents one of the key factors limiting the ultimate sensitivity in laser-based systems for sensing and telecommunication. For advanced app…
