Abstract

Optical frequency combs based on quantum cascade lasers have recently been demonstrated in the mid- and far-infrared spectral regions, opening the possibility for broadband, compact spectrometers. The successful operation of these systems will depend on understanding the frequency noise of these lasers, whose mode-locking dynamics leads to an almost constant optical power rather than pulse generation. We demonstrate that the four-wave mixing process—responsible for comb formation—effectively correlates the quantum frequency noise of the individual comb modes. The plateau observed in the high-frequency portion of the noise spectrum is attributed to the quantum noise limit. This result proves that four-wave mixing introduces no additional frequency noise, showing that quantum cascade laser combs are well suited for high-resolution spectroscopy applications.

Top: Experimental setup used to measure the FNPSD of the laser. The main optical components include the laser (a multistack InGaAs/InAlAs QCL), the optical isolator, the high-finesse optical cavity, and the high-sensitivity MCT detector. The signal is processed by a high-sampling rate oscilloscope. Bottom: Power-versus-current curve of the QCL at fixed temperature. Two operating regimes are observed in this device, a single-mode regime and a comb regime.

Fig. 2.

Schematic of the optical cavity and of the comb spectra with (a) Vr1.0 (comb regime: one mode) and (b) Vr=1.0 (comb regime: all modes). (c) Cavity transmissions acquired in the three conditions: single-mode QCL, QCL in comb regime with only one mode in resonance with the cavity, and QCL in comb regime with all the modes in resonance with the cavity. These acquisitions are obtained by scanning the cavity length. The cavity detuning is the variation of the resonance frequency (FSR) with the length. The comb is composed of many modes, but the most intense ones are six. Essentially only these main modes contribute significantly to the orange transmission peak. On the other hand, only the most intense mode (the one in resonance) contributes to the blue peak. These peaks are used for the calibration of the FA converter (see section 1 of Supplement 1).

(a) FNPSD of the QCL-comb taken in three different conditions. The spectra are compensated for the FA converter cutoff. The technical contributions to the noise are also reported: taking into account the detection noise floor shape, the spectra are reliable up to 2 MHz; the two contributions, one given by the current driver and the other one related to the intensity noise, are negligible. (b) Zoom of the flattening portion of the spectra around 1 MHz, corresponding to the Schawlow–Townes limit. The spectra are related to the two operating conditions of the laser: single-mode with P=15mW (blue) and comb regime (with all the modes in resonance with the cavity) with P=25mW (orange).
