The density profiles of two component Bose-Einstein condensate (BEC) are studied across the trap using the microscopic interaction with Laguerre-Gaussian (LG) beam. We consider $^{87}$Rb BEC in two hyperfine spin states as components and the wavelength of the LG beam is comparable to the atomic de-Broglie wavelength. Competitions between intra- and inter-component interactions produce interesting density structures of the ground state of BEC. Properties of the BEC components are realized from the estimation of the Rabi frequency of two photon stimulated Raman transition over the inter-coupling strengths. We demonstrate interference of vortex-antivortex in terms of inter-component interactions when both the components are subjected to appropriate Raman transitions.
