Scaling of the photon noise in semiconductor cascade lasers
نویسندگان
چکیده
Semiconductor cascade lasers have larger photon noise than conventional semiconductor lasers as a result of positive correlations in photon emission in different gain stages which are connected electrically in series. The photon noise of a cascade laser can be related to the photon noise of a single-stage laser with a scaled external circuit impedance. This scaling relation for the photon noise holds for bipolar as well as unipolar cascade lasers.

Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper.

Two equations were derived to calculate the noise and modulation response. Calcula...
متن کاملPhoton noise and correlations in semiconductor cascade lasers
A comprehensive model for photon noise and correlations in semiconductor cascade lasers is presented. Photon emission events in different gain sections of cascade lasers are correlated. These correlations are found to be positive and arise because the gain sections are connected electrically. The scaling of photon correlations and intensity noise with the number of cascade sections is discussed...

A comprehensive model for the photon number fluctuations and the current noise in quantum cascade lasers is presented. It is shown that the photon intensity noise in quantum cascade lasers exhibits little amplitude squeezing even when noise in the drive current is suppressed below the shot noise value. This is in contrast to interband semiconductor diode lasers in which the laser intensity nois...

A model for the photon noise and the current noise in quantum cascade lasers is presented. It is shown that compared to diode lasers quantum cascade lasers exhibit much less photon-number squeezing even when the noise in the drive current is suppressed well below the shot-noise value. The theoretical model presented in this paper self-consistently accounts for the suppression of the current noi...

We present investigations of the the relative intensity noise (RIN) of a quantum cascade laser (QC) laser in continuous wave operation. We analyze the intensity noise properties in terms of the relative intensity noise (RIN). In contrast to conventional interband semiconductor diode lasers we obtain a different scaling behavior of RIN with increasing optical output power for QC lasers. From a s...
