Abstract :
We demonstrated high-order mode suppression with temperature-profile control in micro-heater-integrated VCSELs. A far-field pattern was changed from a double-peak-pattern to a single lobe with compensating a thermal-lens-effect. The estimated near-filed spot-size could be expanded to 16 μm, which is larger than other monolithic structures.
