Abstract
An number of parameters, such as gain, modulation response, linewidth enhancement factor and relative intensity noise in modulation-doped InGaAsP quantum well (QW) laser emitting at 1.55 μm have been theoretically investigated. The results indicate that the relaxation oscillation frequency for p-type modulation doped QW laser is enhanced by a factor of more than 2 compared to that for undoped MQW lasers. The linewidth enhancement factor of p-type modulation doped QW laser is reduced to ½ of that of undoped MQW laser and the relative intensity noise (RIN) is reduced by a factor of > 10 dB compared to that for undoped MQW lasers.
