Abstract
High peak-power, room-temperature operation is reported for ridge waveguide quantum cascade lasers (QCLs) monolithically integrated onto a silicon substrate. The 55-stage laser structure with an AlInAs/InGaAs core and InP cladding was grown by molecular beam epitaxy directly onto an 8-inch diameter germanium-coated silicon substrate template via a III–V alloy metamorphic buffer. Atomic force microscope imaging demonstrated a good quality surface for the full QCL structure grown on silicon. Fabricated 3mm by 26µm lasers operate at room temperature, deliver more than 3W of peak optical power, and show approximately 3% wall plug efficiency and 4.3 kA/cm2 threshold current density with emission wavelength centered at 11.5µm. The lasers had a high yield with only around 15% max power deviation and no signs of performance degradation were observed over a 10h burn in period at maximum power. Singled-lobed high quality output beam was measured for 3mm by 22 µm devices. Correlation between laser performance and defect density in the laser core for several QCL structures grown on lattice-mismatched substrates will also be discussed in this talk.
