InAlGaAs/InP-based all-monolithic 1.3 µm VCSELs operating continuous wave up to 18°C are demonstrated. The whole structure is grown by a single step of MOCVD. Selective wet etching of an InP layer is used to form an air-gap aperture for the current confinement. The threshold current of an 8 µm device at 15°C is ∼2.8 mA.
