         2 . The optoelectronic system of  claim 1 , further comprising an adhesive arranged between the optoelectronic element and the reflecting layer. 
     
     
         3 . The optoelectronic system of  claim 2 , wherein the adhesive comprises silicone. 
     
     
         4 . The optoelectronic system of  claim 1 , wherein the wavelength converting material is arranged to surround the plurality of lateral surfaces. 
     
     
         5 . The optoelectronic system of  claim 1 , wherein the wavelength converting material directly contacts the plurality of lateral surfaces. 
     
     
         6 . The optoelectronic system of  claim 1 , wherein the wavelength converting material exposes the first electrode. 
     
     
         7 . The optoelectronic system of  claim 1 , wherein the wavelength converting material comprises different kinds of phosphors. 
     
     
         8 . The optoelectronic system of  claim 1 , wherein the reflecting layer is a sheet-like structure. 
     
     
         9 . The optoelectronic system of  claim 1 , wherein the reflecting layer has a portion extending beyond at least one of the plurality of lateral surfaces. 
     
     
         10 . The optoelectronic system of  claim 1 , further comprising a fan-out electrode electrically formed on the first electrode and arranged on the wavelength converting material. 
     
     
         11 . The optoelectronic system of  claim 1 , wherein the wavelength converting material has a sidewall through which light emitted from the optoelectronic element is configured to escape from the optoelectronic system. 
     
     
         12 . The optoelectronic system of  claim 1 , wherein the wavelength converting material comprises a first phosphor layer and a second phosphor layer overlapping the first phosphor layer. 
     
     
         13 . The optoelectronic system of  claim 2 , wherein the adhesive and the reflecting layer are laterally coplanar with each other. 
     
     
         14 . The optoelectronic system of  claim 1 , further comprising a substrate arranged on the reflecting layer. 
     
     
         15 . The optoelectronic system of  claim 1 , wherein the optoelectronic element further comprises a second electrode arranged on the bottom surface. 
     
     
         16 . The optoelectronic system of  claim 1 , further comprising a submount which the optoelectronic element is bonded to.
