Abstract
The use of expanded mode layers in lasers designed for DVD read/write applications is investigated and their performance is compared with that of a more conventional structure. The expanded mode design achieves a higher confinement factor and hence much lower threshold currents than the conventional structure, for the same measured vertical farfield divergence of 18deg. T0 is increased from 51 to 65 K (20-70degC) for the expanded mode structure for 320-mum long devices with uncoated facets. It is also found that zinc or magnesium can be used interchangeably for the p-dopant in a given structure without any impact on device performance.
