a Splitting structure of states occurring in the super-lattice with much more Si-Ge nanolayers. b Emission peaks with multi-longitudinal-mode appearing in the super-lattice (composition: 2(Si)/1(Ge) in (100) direction) measured in room temperature. c Emission peaks with multi-longitudinal-mode appearing in the super-lattice (composition: 1(Si)/2(Ge) in the (111) direction) measured in 20 K
