Abstract :
Summary form only given. We demonstrate intersubband absorption in p-type InGaAs-AlAs QWs at normal incidence for light polarized along the (100) direction between two heavy hole (HH) states and between HH and spin orbit split off hole (SO) states. To the best of our knowledge, such transitions between HH and SO states have not been reported in quantum wells. Our transition energies range from 260-540 meV (4.8-2.3 μm). These transitions could be used for frequency conversion
