here, we propose an optical filter and an optical power splitter based on two-dimensionalphotonic crystal all circular ring resonators. these structures are made of a square lattice ofsilicon rods with the refractive index n1=3.464 surrounded by air (with refractive indexn2=1). first, we have designed the filter and by using that, we designed a power splitter. thetransmission efficiency and qua...

In this paper, we propose a new time-shared twin memristor crossbar for pattern-recognition applications. By sharing two memristor arrays at different time, the number of memristor arrays can be reduced by half, saving the crossbar area by half, too. To implement the time-shared twin memristor crossbar, we also propose CMOS time-shared subtractor circuit, in this paper. The operation of the tim...

This paper proposes a promising technique to compensate chromatic dispersion (CD) by using an optical all pass filter (OAPF) as an optical equaliser. The phase response of OAPF will be designed to cancel the phase delay of single mode fibre (SMF) which is the main cause of CD. The simulation of the mathematical model of the optical communication system at 10 Gb/s employing the proposed OAPF wil...

Artificial intelligence has made people’s demands for computer computing efficiency increasingly high. The traditional hardware circuit simulation method neural morphology computation problems of unstable performance and excessive power consumption. This research will use non-volatile flash memory cells that are easy to read write build a convolutional network structure improve the morphologica...
