Abstract :
In this paper, conventional InP-based BTJ-VCSELs with epitaxial output mirror and emission wavelengths for optical applications at 1.3 μm and 1.55 μm show excellent stationary and dynamic characteristics including output powers well beyond 1 mW at 90°C in conjunction with wide eye openings at 10 Gbit/s modulation rate as well as room temperature data rates up to 25 Gbit/s. In future work, we plan to enhance the modulation rate up to 40 Gbit/s and to increase the operating temperature range for ultra-high bandwidth lasers.
