| Theresearchproduceatheoreticalstudyfordesigningnewlogical gates based on laser source. As known 1'et, the design of the processor depends of logical gates, rvhich represent the basic component of its architecture. The speed ofthe processor depends on how the layout designs ofthelogicalelectroniccircuit(processorarchitecture),anddependonthe speedoftlreelectricalsignaltravelingtlrroughofthegates.Since,thebasic elementsofthegatesarenranufacturedfiornasemiconductormaterials, tlrentheelectricalsignalspassestlrrouglritneedsacertaintimewhich considerveryshortforasirrglegatebutitisnoticedforoverallthe processor chip. Besides, there is a heat problent due to the electrical signals traveling through the senlicottductor ntaterial' Replacing these electronic gates by a laser gates gives increasing of the speed of passing signal through the gate' and then reducing the processitrgtinleforalltlrcproccssorrr'itlrouthighincreasirrgirr temperature. Theobjectiveoftlrisresearchistobuildupatheoreticaldesigrrof laser logical gates instead of the electronic logical gates to ensure high $,ork efticiency for the processor. Since the designing of the three known gates(NoT,oR,andANDgates)isdonetlreoreticallyusinganoptical elements instead of electronic elements. The laser logical gate components aredesignedusingasinglenrainfeedinglasersource,filters,reflectors, linear polari zer, andphase rotator polarizer' Photo detectors can be used to receivethelasersignats.Theprocessorlalotttsbasedorrlasergatesensure a very high speed near to the speed of light because the used signal is electromagnetic waves not an electrical signal | ||
