  We propose an optical scheme to build an entangled network composed of $W$
state based on polarization encoded qubits (photons). This new setup consists
of 2 $cNOT$ gates, 4 $V$ gates, 2 $Hadamard$ gates and basic optical tools such
as polarizing beamsplitters ($PBS$s) and path couplers ($PC$s). $V$ gate is a
specially-designed tool acting as a two-qubit gate which is composed of a
$cNOT$ gate, 3 $PBS$s and a $PC$. By using this gate, one benefits from the
temporarily generated optical degree of freedom, which is the spatial mode of a
photon in the proposed scheme. Using an extra degree of freedom allows us to
perform more capable processing for $W$-state creation protocols. We use four
photons as input, which means we do not need entanglement as a resource. Also,
we show that the proposed scheme can be implemented by operating the quantum
optical gates which can be realized via current photonics technology.
