MULTIMODE MONOLITHIC VERTICAL CAVITY SURFACE EMITTING LASER ARRAY AND LASER SYSTEM INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a monolithic VCSEL array in which VCSELs are configured to emit laser beams at different wavelengths, respectively.;SOLUTION: A monolithic surface emitting laser array includes a reflector 104, a light emitting layer 102 and a diffraction grating layer 112 configured to use two or more nonperiodical subwavelength diffraction gratings. Each diffraction grating is configured to form a cavity resonator together with the reflector. Each diffraction grating is configured to use a diffraction grating pattern achieving one or more internal cavity modes and achieving one or more external transverse modes emitted through the diffraction grating.;SELECTED DRAWING: Figure 1A;COPYRIGHT: (C)2016,JPO&INPIT
