DESIGN OF A WIDEBAND 1×2 Y-BRANCH OPTICAL BEAM SPLITTER USING GaAs BASED PHOTONIC CRYSTAL

In this paper we have designed a two dimensional GaAs based photonic crystal Y-branch beam splitter which has one input terminal and two output terminals. Using single mode light source and FDTD analysis we have found a higher bandwidth valued 78% and also increased output power efficiency which is valued 93%. This increased bandwidth will give us faster data transfer capability which can be a great aspect for respective communication system.
