Abstract :
The authors show that, by introducing a single focused ion beam etched cavity into the 1.3 μm bandgap material between the phase tuning and sampled grating sections of a three section DBR laser, sufficient feedback is produced to enable stimulated emission at 1.3, as well as 1.55 μm. The etched cavity also increases the inter-contact resistance
