Stable in-Phase Mode Operation in Coherent VCSEL Array With an Integrated Phase Shifter

Implant-defined coherent vertical-cavity surface-emitting laser (VCSEL) arrays with an integrated phase shifter that can convert the out-of-phase mode into the in-phase mode were demonstrated. The measured angular full-width at half-maximum (FWHM) from a {9} \times {9} coherent VCSEL array in the...
