Pulsed 25-108/spl deg/C operation of GaInNAs multiple quantum well vertical cavity lasers

Summary form only given.GaAs-based vertical cavity surface emitting laser (VCSEL) diodes are becoming increasingly important in transmitters. By using GaInNAs MQW active regions, the emission wavelength of GaAs-based lasers can be extended into the range of 1200-1300 nm. In addition, the reduced temperature sensitivity of this active region allows for the possibility of uncooled transmitter operation.
