Abstract :
Vertical cavity surface-emitting laser (VCSELs) have large mode spacing due to the very short cavity and are particularly suitable for continuous wavelength tuning. In addition, the low threshold currents, low beam divergence angles, and their ability to form two-dimensional arrays make them attractive for free-space optical interconnect applications. In this paper, we demonstrate a continuously tunable, individually addressable 8×6 VCSEL array using integrated heaters. VCSELs with a mesa size of 12 μm×12 μm exhibit a threshold current of 4.2 mA, output power of 1.2 mW (cw, room temperature), and continuous tuning range of 10 nm are obtained
