Abstract:

The authors reported the first observation of distributed feedback lasing in a pulsed homojunction GaAs injection laser. Feedback was achieved via a third order grating structure which was ion machined in the top surface of the p-type layer. Laser action was observed at 8420 A and 8459 A corresponding to grating periodicities of 3548 A and 3572 A, respectively. Threshold current densities at 77K were observed to be as low as approximately 5700 A per sq cm.
