High-temperature optically pumped 1.55-μm VCSEL operating at 6 Gb/s

Vertical cavity lasers operating at a wavelength of 1547 nm were optically pumped by a 980-nm diode laser. Continuous-wave fiber-coupled output powers of 2 mW at room temperature and 140 nW at 105/spl deg/C were observed. Fiber optic transmission over 25 km at 6 Gbit/s with a power penalty of 0.3 dB was demonstrated.
