Uncooled 25-Gb/s transmission of a 1.3-µm surface-emitting laser is demonstrated. A fabricated laser, which consists of an InGaAlAs-MQW DFB active stripe and surface-mountable structure, exhibited clear 25-Gb/s eye openings after 2-km SMF transmission up to 85°C.
The uncooled 25-Gbit/s direct modulation of a 1.3-μm horizontal-cavity surface-emitting laser was demonstrated. A fabricated laser, which is directly mountable on a high-frequency coplanar line, exhibited 25-Gbit/s eye openings up to 100°C.
Circular, narrow beam emission of a lens-integrated surface-emitting laser operated at 1.3-mum wavelength was demonstrated. The laser consists of a distributed feedback laser cavity monolithically integrated with an etched 45deg total reflection mirror and an etched InP lens. The profile of the etched InP lens was estimated to be a highly symmetrical parabolic shape that is ideal for the collimation...
