Abstract
The temperature dependence and power output of vertical-cavity surface-emitting lasers (VCSEL's) are of great importance when considering these devices for real applications. We have deliberately offset the peak wavelength of the quantum well from the wavelength of the device cavity mode so that they are aligned at elevated temperatures. The result of this design change is to produce an 8 µm diameter VCSEL capable of operation to 145°C, as well as CW operation of broad area (70 µm diameter) heat-sunk devices to record power levels. Fiber coupling experiments were also carried out, and a record 33 mW CW power was coupled to a multimode fiber.
