| 英文摘要 | PURPOSE:To reduce the oscillating frequency variation of a laser when an analog modulation is performed by adding a resonator out of a semiconductor laser and setting a laser chip length, the external resonator length, an LD end reflectively, and external resonator reflectivity to specific ranges. CONSTITUTION:A laser light 104 emitted from the resonator end 103 of a semiconductor laser 101 of an active layer 102 is reflected by a concave mirror 105 as an optical element having reflecting function, and the reflected light 106 is fed back to the laser 10 The chip length (l)107 of the laser, the refractive index n1 of the active layer 102, the amplitude reflectivity r0 considered with the feedback coupling degree to the laser of the mirror 105, the amplitude reflectivity r1 of the end face 103 of the resonator, and the distance L108 from the end 103 to the mirror 105 are set to r0>=0.1, L/n1l>=0.9, preferably r0>=0.2, L/n1l>=5, and, for example, to r1<=0.565. |
