Claim Text:
1. A semiconductor device ( 1 ) for use in at least an optical application comprising: at least an optically passive aspect ( 2 ) that is operable in substantially an optically passive mode, and at least an optically active material ( 3 ) comprising at least a material that is operable in substantially an optically active mode, wherein: the optically passive aspect ( 2 ) further comprises at least a crystalline seed layer ( 4 ), the optically active material ( 3 ) being epitaxially grown in at least a predefined structure ( 5 ) provided in the optically passive aspect ( 2 ) that extends into the crystalline seed layer ( 4 ) to at least an upper surface ( 4 ′) of the crystalline seed layer ( 4 ), and the optically passive aspect ( 2 ) is structured to comprise at least a passive photonic structure ( 6 ), wherein the crystalline seed layer ( 4 ) comprises a crystalline wafer and wherein the optically active material ( 3 ) comprises at least one of: a III-V material and a II-VI material.
