We present the first 865 \mu m continuum image with sub-arcsecond resolution obtained with the Submillimeter Array .
These data resolve the Orion-KL region into the hot core , the nearby radio source I , the sub-mm counterpart to the infrared source n ( radio source L ) , and new sub-mm continuum sources .
The radio to submillimeter emission from source I may be modeled as either the result of proton-electron free-free emission that is optically thick to \sim 100 GHz plus dust emission that accounts for the majority of the submillimeter flux , or H ^ { - } free-free emission that gives rise to a power-law spectrum with power-law index of \sim 1.6 .
The latter model would indicate similar physical conditions as found in the inner circumstellar environment of Mira variable stars .
Future sub-arcsecond observations at shorter sub-mm wavelengths should easily discriminate between these two possibilities .
The sub-mm continuum emission toward source n can be interpreted in the framework of emission from an accretion disk .
