“…The design of a SOA-based system requires careful consideration of the operating wavelength and input power because these factors have an impact on the gain saturation limits. Analysis is performed in the C-band at 1 Tbps, and 1500 nm offers the best output gain for the proposed design 21 , 22 . The sample timing diagrams are given in Figs.…”

“…The results obtained in our previous works 21 , 22 to design all-optical gray converter for binary and BCD inputs using SOA in the MZI configuration are compared with the results obtained using PhC-SOA in the MZI structure. The variation in construction and operation is the basic difference between these two types of SOAs.…”

Future communication networks require the entire communication system to be all-optical to overcome the bandwidth constraints of electronics. All-optical devices play a vital role in supporting future networks, which demand a high speed of up to Tbps. An all-optical gray code converter operation was demonstrated numerically using a photonic crystal semiconductor optical amplifier (PhC-SOA) in a Mach-Zehnder interferometric (MZI) configuration at 1 Tbps for M-ary differential phase shift keying modulated binary and BCD inputs. The design achieved a very high extinction ratio of about 123.8 dB with a good quality factor value of about 45. The results show that PhC-SOA-based XOR and OR gates in the gray code converter design exhibits improved modulation features compared with traditional SOAs in our previous works.

The adder is a highly fundamental part of the central processing unit. The carry lookahead adder (CLA) has become the fastest adder used in digital circuits. For high-speed operations, optical computing has become an essential research field. In this manuscript, a microring resonator (MRR)-based all-optical (AO) CLA is proposed and analyzed. The MRR-based AO design is capable of getting a higher operational speed to fulfill the demands of end users. The Z domain's mathematical model of the CLA is developed using the unit delay signal processing method. The numerical simulations validate the proposed circuit's operational speed of close to 260 Gbps. The parameters for this design are chosen optimally to enable it to be effectively implemented for optical computations.
