Abstract
The operation of a branching waveguide stripe‐geometry semiconductor injection laser is described. This structure produces interference fringes in the far field which are spatially scanned by electrically varying the optical phase in each leg of the branched waveguide in a manner analogous to microwave phased array radar. Moreover, the output spectral peak of the laser also varies periodically over 70 Å with these electrically induced phase shifts.
