Abstract
A device includes: a laminate including first and second regions adjacent to respective both sides of an isolation groove; a mesa stripe structure adjacent to the first region on the laminate and extending in the first direction; a bank structure adjacent to the second region on the laminate and extending in the first direction; and an electrode pattern. The isolation groove has an inner surface including a first wall surface adjacent to the first region, a second wall surface adjacent to the second region, and a bottom surface between the first and second regions. The ridge electrode extends from the side of the mesa stripe structure, along a second direction, toward the bank structure, and not beyond the second wall surface. The connection electrode is narrower in width in the first direction than any one of the ridge electrode and the pad electrode.
