Abstract :
We have investigated the effects of current blocking layers in 10 Gb/s 1.3 μm DFB lasers in view of the slope efficiency and the modulation bandwidth. It is experimentally shown that the current blocking structure consisting of p-InP(clad)/n-InP/i-InP/n-InP/i-InP/n-InP(sub.) gives a high slope efficiency as well as a large modulation bandwidth of above 10 GHz at 70 °C.
