フォトニック結晶によるVCSELの横モード制御

抄録

Approaches for controlling the lateral mode of vertical cavity surface emitting lasers by photonic crystal like structures are reviewed. Both the holey fiber structure and the triangular hole structure has been reported to be effective in enlarging the emission area of single lateral mode oscillation. Although the resulting optical power is limited so far, the capability of in-phase evanescent coupling between multiple cavities by the hole arrangement gives potential for realizing a high power, single coherent light source.
