According to the font properties of Calibri, the font is designed by Luc(as), and the Hebrew OpenType layout logic is developed by Ralph Hancock and John Hudson.
The layout logic for Biblical Hebrew (not the outlines) is open source software under the MIT License.
It is of course embedded in the font, so a font editor like FontCreator can provide access to it. If you don't have a font editor, then I'm sure John Hudson can help you further.
