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 8):
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 including a single first group containing one or more InAs molecular layers, a single second group containing one or more GaSb molecular layers, one or more third groups containing one or more GaSb molecular layers, and one or more fourth groups containing one or more InSb molecular layers, in each unit structure, any of the third groups being disposed between the single second group and one of one or more fourth groups, and in the light absorbing layer, the single second group being disposed between the single first group and all the third groups.
