  We study spin Hall effect in a three terminal Y-shaped device in presence of
tunable spin-orbit (SO) interactions via Landauer-B\"{u}ttiker formalism. We
have evolved a fabrication technique for creating different angular separation
between the two arms of the Y-shaped device so as to investigate the effect of
angular width on the spin Hall conductance (SHC). A smaller angular separation
yields a larger conductance. Also arbitrary orientation of the spin
quantization axes yields interesting three dimensional contour maps for the SHC
corresponding to different angular separation of the Y-shaped device. The
results explicitly show breaking of the spin rotational symmetry. Further a
systematic study is carried out to compare and contrast between the different
SO terms, such as Rashba and Dresselhaus SO interactions and the interplay of
the angular separation therein.
