Abstract :
The first electrically pumped 1.55 μm multiple wavelength VCSEL array is demonstrated. The wafer bonded array consists of four channels operating between 1509 and 1524 nm. Multiple wavelengths were defined using an etched intracavity superlattice prior to bonding. Threshold currents of 0.9 mA and peak output powers of 0.45 mW were measured
