Abstract:
1. A radiation-emitting-and-receiving semiconductor component comprising: at least a first semiconductor layer construction and a second semiconductor layer construction which are arranged spaced apart from one another in an integrated manner on a common substrate; the first semiconductor layer construction having a first semiconductor layer sequence comprising an electromagnetic-radiation-generating region, n-conducting semiconductor layers and p-conducting semiconductor layers; said n-conducting semiconductor layers being arranged between the common substrate and the electromagnetic-radiation-generating region and said p-conducting semiconductor layers being arranged on a side of the electromagnetic-radiation-generating region which is remote from the common substrate; the second semiconductor layer construction having a first semiconductor layer sequence and a second semiconductor layer sequence; the first semiconductor layer sequence of the first semiconductor layer construction corresponding to the first semiconductor layer sequence of the second semiconductor layer construction and having the same composition; the second semiconductor layer sequence comprising an electromagnetic-radiation-absorbing region and a stack of p-conducting semiconductor layers; and the electromagnetic-radiation-absorbing region being n-conducting and being arranged between said stack of p-conducting semiconductor layers and the p-conducting semiconductor layers of the first semiconductor layer sequence, wherein said electromagnetic-radiation-generating region has a composition which is different from that of the electromagnetic-radiation-absorbing region, and wherein the electromagnetic-radiation-generating region and the electromagnetic-radiation-absorbing region are electrically connected to a common contact arranged on a part of the electromagnetic-radiation-generating region that faces the common substrate.
