We have calculated the gain function of a type-II W-design AlSb/InAs/GaAsSb/InAs/AlSb quantum wells to be used in an active region of interband cascade lasers, for two linear polarizations of in-plane propagating light: transverse-electric and transverse-magnetic. The effect of external electric field, imitating the conditions in a working device, has also been taken into account. We have proposed an active region design suitable for practical realization of mid-infrared lasing devices with controllable polarization properties. We have also demonstrated a way to achieve polarization-independent gain in mid-infrared emitters, which has not been reported so far.

“…It was showed with calculations and experimental results that the optical mode intensity in the active region could be increased in the shortened injector IC laser to improve the device performance. 49 This group has worked on Sb-based type-I QW lasers for many years and recently began efforts in the development of IC lasers on n -type GaSb substrates using an Eiko EV100S solid source MBE chamber. The group reported their initial work in IC lasers in 2009.…”

“…The QCL is based on strain-compensated InGaAs/InAlAs-AlAs material system on InP, which has the advantage of a more mature InP substrate and no Sb-containing alloys compared to other 3.3 μm quantum cascade [9,10], interband cascade [11,12], and type-I diode lasers [13] reported up to now. It is thermoelectrically stabilized at 300 K and operates in a pulsed mode, with a pulse width of 100 ns and 20 kHz repetition rate.…”

Highly sensitive and fast detection of propane–butane using a 3 μm quantum cascade laser

et al. 2013

View full text Add to dashboard Cite

A mid-IR optical analyzer based on a 3 μm Fabry-Perot quantum cascade laser has been developed for ultrafast detection of aerosol propellants, such as propane and butane. Given the laser emission bandwidth of 35 cm(-1), the system is spectrally well-matched to the C-H vibrational band of hydrocarbons, it is insusceptible to water interference, and stable enough to operate without wavelength scanning. Thus, it offers both high sensitivity and speed, reaching 1 ppm precision within a measurement time of 10 ms. The performance of the instrument is evaluated with an industrial demonstrator for aerosol cans leak testing, confirming that, in compliance with international directives, it can detect leaks of 1.2×10(-4) slpm at a rate of 500 cans per minute.
