Reduction of Quantum Noise in Very Narrow Planar Stripe Lasers

概要
- 論文の詳細を見る
Quantum noise observed in the light output of semiconductor lasers was dramatically reduced by making the stripe width narrower than 5 μm. The suppression of the shot noise resonance in the narrow planar stripe lasers (NPS laser) was qualitatively explained by the buffer effect brought about by the increased spontaneous emission which goes into the lasing modes. The increased spontaneous emission also plays a role to suppress the relaxation oscillation in the NPS laser. Neither the intensity fluctuation due to the self-pulsation nor the partition noise resulting from the transverse multimode oscillation was observed owing to highly uniform excitation and the excellent transverse-mode control in the NPS lasers.
