Qcl wafer
WebFeb 1, 2014 · The THz QCLs were processed into the surface-plasmon ridge waveguide structures using standard photolithography and wet chemical etching techniques. Ridges with widths ( w) ranging from 145 to 425 μm were formed, and the substrate was thinned to ∼180 μm by wet chemical etching. WebOct 23, 2013 · For the fabrication of wafer bonded THz QCLs with SI-SP waveguide, one active region chip is flipped upside down on top of the other one (see Fig. 2(a)). In order to be able to use the same active region on top and bottom, a symmetric QCL design, showing the same operation conditions at both bias directions, is necessary. 21 21. C.
