We report experimental evidence of Second-harmonic generation (SHG) due to intersubband transitions in \(G a A s / A l_{x} G a_{1-x} A 8\) step quantum wells using a multipass or "waveguide" structure. A SHG conversion efficiency of \(3.46 \times 10^{-4}\) has been achieved which is one order of mag
