GaAs/AlGaAs multiple-wavelength vertical-cavity laser arrays on p substrates with periodic wavelength variations

Summary form only given. We demonstrate GaAs-AlGaAs multiple wavelength (MW)-VCSEL arrays on p substrates with periodic wavelength variations for the first time. We achieved cw lasing wavelength span of 24 nm, threshold current <5 mA, and output power >3 mW. With further design and growth optimization, these MW-VCSEL arrays will have practical use in cost-effective WDM LAN applications.
