Coating for DFB/DBR laser diodes |
August 21, 1990 |
| In DFB/DBR semiconductor diode lasers, competition may arise between the DFB (Distributed Feed-Back) mode corresponding to the period of the grid present and the FP (=Fabry-Perot) mode determined by the relative distance of the mirror surfaces, as a result of which the laser does not ope |
