Abstract

A new configuration of an all optical (2 input) NOR gate
based on two-dimensional photonic crystals is proposed.
The structure is based on 20*20 rods of silicon in the
background of air. The square-ring resonator shaped
structure contains three inputs and one output port. Three
input ports (Ctrl, A and B) are introduced in to the
structure for achieving the appropriate application. In
order to investigate the functionality of the structure
(functioning as a logic NOR gate), photonic band gap
(PBG), field distribution and transmitted power spectrum
are considered. PBG and field distribution are obtained
considering the plane wave expansion and finite
difference-time-domain methods, respectively. All the
states of a NOR gate (truth table or logical values) are
considered by applying related inputs to the input ports
(incident field with the wavelength in the PBG region).
The bit rate, normalized intensity and rise time of
2.5Tbit/s, 99% and 2ps, are azlso obtained for the gate.
The obtained logic NOR gate can be an appropriate
candidate for utilization in optical integrated circuits.
