We theoretically study the absorption in grating coupled quantum wells in a cavity. We describe the coupling between the three oscillators present in the structure: the intersubband transition, the grating and cavity modes. We show that optical mode anticrossings should be observed. The splitting between the cavity mode and the intersubband transition is calculated but its experimental observation would require electronic coherence times longer than what was measured.
