Abstract:
A light receiving device includes a light absorbing layer. The light absorbing layer includes multiple unit structures. Each unit structure has an InAs portion, a first GaSb portion, an InSb portion, and a second GaSb portion, which are arranged in a direction of an axis. One of the group-III atomic plane and the group-V atomic plane in the first GaSb portion is bonded to another of the group-III atomic plane and the group-V atomic plane in the InAs portion. One of the group-III atomic plane and the group-V atomic plane of the InSb portion is bonded to another of the group-III atomic plane and the group-V atomic plane of the first GaSb portion. One of the group-III atomic plane and the group-V atomic plane of the second GaSb portion is bonded to another of the group-III atomic plane and the group-V atomic plane of the InSb portion.

Claim (Index 1):
A light receiving device comprising:\n a first conductivity-type III-V compound semiconductor layer; a second conductivity-type III-V compound semiconductor layer; and a light absorbing layer disposed between the first conductivity-type III-V compound semiconductor layer and the second conductivity-type III-V compound semiconductor layer, the light absorbing layer including multiple unit structures arranged in a direction of an axis to form a type-II superlattice, each unit structure having an InAs portion, a first GaSb portion, an InSb portion, and a second GaSb portion arranged in the direction of the axis, the InAs portion having multiple InAs molecular layers arranged in the direction of the axis, the first GaSb portion having a GaSb molecular layer, the first GaSb portion having a group-III atomic plane and a group-V atomic plane, the InAs portion having a group-III atomic plane and a group-V atomic plane, one of the group-III atomic plane and the group-V atomic plane in the first GaSb portion being bonded to another of the group-III atomic plane and the group-V atomic plane in the InAs portion, the InSb portion having an InSb molecular layer, the InSb portion having a group-III atomic plane and a group-V atomic plane, the InSb portion having a group-III atomic plane and a group-V atomic plane, one of the group-III atomic plane and the group-V atomic plane in the InSb portion being bonded to another of the group-III atomic plane and the group-V atomic plane in the first GaSb portion, and the second GaSb portion having a GaSb molecular layer, the second GaSb portion having a group-III atomic plane and a group-V atomic plane, one of the group-III atomic plane and the group-V atomic plane in the second GaSb portion being bonded to another of the group-III atomic plane and the group-V atomic plane in the InSb portion.
