High Speed Integrated Circuits for High Speed Coherent Optical Communications

High Speed Integrated Circuits for High Speed Coherent Optical Communications by Hyun-chul Park With the development of (sub) THz transistor technologies, high speed integrated circuits up to sub-THz frequencies are now feasible. These high speed and wide bandwidth ICs can improve the performance of optical components, coherent optical fiber communication, and imaging systems. In current optica...

Design of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...

Integrated all-optical logic discriminators based on plasmonic bandgap engineering

Optical computing uses photons as information carriers, opening up the possibility for ultrahigh-speed and ultrawide-band information processing. Integrated all-optical logic devices are indispensible core components of optical computing systems. However, up to now, little experimental progress has been made in nanoscale all-optical logic discriminators, which have the function of discriminatin...

Power Aware & High Speed Booth Multiplier based on Adiabatic Logic

Multiplier is one of the major arithmetic operations carried out in DSP applications. This paper presents a modified Booth multiplier based on adiabatic logic. It is composed of Booth encoder, multiplier containing partial product generators and 1-bit (half and full) adders and final adder. Booth multiplication allows for smaller, faster multiplication circuits through encoding the signed numbe...
