Active Distributed Reflector Lasers Phase Adjusted by Groove Region
スポンサーリンク
概要
- 論文の詳細を見る
Active distributed reflector lasers, where the phase adjustment is accomplished by a groove in the middle part of the cavity, are proposed. Design considerations for the groove are given. Phase adjusted lasers emitting at 1.5 μm were fabricated using mass transport technique. CW operation at room temperature was achieved and single longitudinal mode spectra were observed. Below-threshold spectra show that the mode degeneracy of conventional DFB lasers is avoided, which indicates that lasing occurs almost at the Bragg wavelength.
