Abstract
A 6-port optical circulator using silicon photonic crystals has been designed and proposed in this paper as an essential component of an optical communication system. The proposed 6-port circulator has greater isolation loss values between the input and isolated ports and lower insertion loss values between the input and output ports. The proposed circulator achieves maximum isolation of -38.7 dB and minimum insertion loss of 0.0029dB. The proposed designs are extremely useful in the telecommunications industry, wavelength division multiplexing and photonic integrated circuits applications due to their low insertion and high isolation losses.
