We demonstrated an electrically pumped InP-based microcavity laser operating in continuous-wave *** active region is designed with antimony surfactants to enhance the gain at 2 μm,and a selective electrical isolation scheme is used to secure continuous-wave operation for the microcavity laser at room *** lasers were fabricated as a notched elliptical resonator,resulting in a highly unidirectional far-field profile with an in-plane beam divergence of less than 2°.Single-mode emission was obtained over the entire dynamic range,and the laser frequencies were tuned linearly with the pumping ***,these directional lasers pave the way for portable and highly integrated on-chip sensing applications.
