Y. Kitaoka et al., MODULATED BLUE 2ND-HARMONIC GENERATION USING DIRECT MODULATION OF DISTRIBUTED-BRAGG-REFLECTOR LASER-DIODE, Electronics Letters, 33(19), 1997, pp. 1638-1639
Modulated blue light was generated by directly modulating a tunable di
stributed Bragg reflector laser diode, which was coupled to a quasi-ph
ase-matched second harmonic generation waveguide in MgO doped LiNbO3.
The peak power of 17mW was measured at a modulation frequency of 20MHz
