O. Kjebon et al., 30GHZ DIRECT MODULATION BANDWIDTH IN DETUNED LOADED INGAASP DBR LASERS AT 1.55 MU-M WAVELENGTH, Electronics Letters, 33(6), 1997, pp. 488-489
An increased resonance frequency and reduced damping of the resonance
peak leading to a record high modulation bandwidth of 30GHz were obser
ved in 1.55 mu m InGaAsP DBR lasers. These results are attributed to t
he mechanism of detuned loading.
