Claim Text:
1. A silicon distributed Bragg reflector (DBR) structure-integrated light device, comprising: a bottom reflector layer formed by alternately stacking two semiconductor material layers having different indices of refraction; an n-type ohmic contact layer formed on an upper surface of the bottom reflector layer; an active layer formed on an upper surface of the n-type ohmic contact layer, and configured to generate light through recombination of electrons and holes injected through at least one oxidizable layer having a current injection hole formed at a center thereof, wherein the at least one oxidizable layer is encompassed by the active layer; a p-type ohmic contact layer formed on an upper surface of the active layer; a top reflector layer formed on an upper surface of the p-type ohmic contact layer and having a silicon DBR structure in which at least one first silicon layer and at least one second silicon layer having different indices of refraction are alternately stacked; and n-type and p-type electrodes formed on the upper surfaces of the n-type and p-type ohmic contact layers, respectively, wherein the first silicon layer has a lower index of refraction than the second silicon layer and is obliquely deposited on the p-type ohmic contact layer to have a varying index of refraction by adjusting an inclination of the first silicon layer, and the second silicon layer is deposited perpendicular to a plane of the p-type ohmic contact layer, and wherein the active layer directly contacts with each of the p-type ohmic contact layer and the n-type ohmic contact layer.
