A. Talneau et al., Agile and fast switching monolithically integrated four wavelength selectable source at 1.55 mu m, IEEE PHOTON, 11(1), 1999, pp. 12-14
We demonstrate 4-nm spaced four emitted wavelengths on a single output wave
guide in a four channel DBR lasers array monolithically integrated with a 4
> 1 coupler, Using distributed Bragg reflector tunability, all wavelengths
within a 16nm range can be reached with an accuracy better than 0.2 mn, Wa
velength switching time measured at 90% of nominal power is 4 ns.
