| Popis: | It is reported on the passivation of the mirror facets, opened in the air, of ridge waveguide InGaAs/GaAs/AlGaAs single quantum well (λ=980 nm) laser diodes. The passivation concept consists of two steps, namely, oxide removal by irradiation of the mirror facets with a pulsed KrF laser, immediately followed by the deposition of a thin silicon layer. The experimental arrangement (the process operation and the aging behavior-resistance to catastrophic optical damage) of the lasers thus treated are described. The structural modification of the laser facets, as probed by micro-Raman spectroscopy and Rutherford backscattering spectroscopy, and the calibration technique used to assess the rate of oxide removal are also presented. |
