Abstract :
The design and fabrication of a laterally-coupled distributed feedback (LC-DFB) laser using a third order grating is presented. The side mode suppression ratio is at least 45 dB for as-cleaved devices with various cavity lengths. We numerically investigate three approaches to reducing the threshold current.
