FP-QCLs can operate at room temperature. The emission is in the same wavelength range as DFB QCLs. i.e. from 740cm-1 to 2390cm-1 with a similar threshold current and voltage. The variation of temperature has minimal influence on the emission bandwidth. This is mainly defined by the supplied current. FP-QCLs are well adapted when broad band emission is acceptable. For example in liquid spectroscopy, high power emitting sources, when no signal purity is required or for using the QCL with external cavities.
Parameters that define a FP-QCL:
- the central wavelength is defined by the centroid of total emitted power
- the bandwidth is defined as the wavelength range where 99% of the power is emitted.
- for the same laser, the central wavelength and the bandwidth can change in function of the operating current and voltage
- the variation of the QCL temperature has minimal influence on the central wavelength and the bandwidth
