Abstract :
In conclusion, we successfully observed S- and N-shaped NDRs by using the R-TOPS simultaneously. Bistabilities originated from S- and N-shaped NDRs were obtained by changing the light input power. We succeeded to realize bistabilities with opposite behaviours in a single device for implementation in an optical logic circuit
