Quelques propriétés optiques du laser tunnel

The cw oscillation of a tunnel laser is demonstrated. The high losses encountered in tunneling systems are here compensated for by a high gain amplifying medium for barrier widths between 0 and λ/2. For a first particular angle of incidence, the TM frequency remains invariant when the total length of the laser is varied. For a higher value of the incidence angle, the frequency associated with the TE polarization increases while the frequency associated with the TM polarization undergoes a negative variation when the total length of the laser is reduced.
