This paper deals with the design and simulation of all-optical 4×2 encoder
using the wave interference effect in photonic crystals. By producing 4 optical
waveguides as input and two waveguides as output, the given structure was designed.
The size of the designed structure is 133.9 μm2. The given all-optical encoder has a
contrast ratio of 13.2 dB, the response time of 0.45 ps, and also the bit transfer rate of
2.2 Tbit/s. The results from these structures suggest the high flexibility of the structures,
their resolution rates, and appropriate response time relative to that of other structures in
this rank as well as their applicability in terms of dividing. To elicit the optical band gap
rage for structure design, the plane wave expansion method and also the
finite difference time domain methods were used to investigate the results from
designed structures.
