Grating-coupled, surface-emitting (GCSE) quantum-cascade lasers (QCLs) of linear geometry generally operate in an antisymmetric mode, which is undesirable due to its double-lobed far-field beam pattern. The antisymmetric mode can be suppressed by des

A three-element phase-locked array of ∼5.3 μm-emitting quantum cascade lasers fabricated by a two-step MOCVD process is demonstrated which operates in a diffraction-limited beam to 5.3 W peak pulsed power. To compensate for overetching at the arra

A numerical model is developed for a phase-locked array of quantum cascade lasers. The population density is derived from rate equations. The temperature distribution for stationary generation is produced by ohmic heating. It is shown that the result

Grating-coupled, surface-emitting (GCSE) quantum-cascade lasers (QCLs) are attractive sources for realizing watt-range continuous-wave (CW) output powers in the mid-infrared spectral region. Linear GCSE QCLs generally operate in the antisymmetric lon

Grating-coupled, surface-emitting (GCSE) quantum-cascade lasers (QCLs) offer a pathway towards realizing watt-range, surface-emitted output powers in the mid-infrared spectral region with high beam quality. Previously we have reported wide-ridge GCSE

A ray optics (RO) technique utilizing diffraction grating theory and a transfer matrix method is used to derive a closed form expression for the 1st-order distributed feedback coupling coefficient in practical quantum cascade laser structures. Values

Five-element phase-locked arrays of 4.7 μ m-emitting quantum cascade lasers are demonstrated which operate either in a near-diffraction-limited (D.L.) beam to 3.6 W peak pulsed power or in a narrow beam (< 3.5 × D.L.) up to 6.1 W peak pulsed power.
