  We present an analysis of the optical response of a class of on-chip
integrated nano-photonic systems comprising all-dielectric building block based
multifunctional light manipulating units (LMU) integrated with quantum dot (QD)
light sources. The multiple functions (such as focusing excitation light, QD
emission rate enhancement, photon guidance, and lossless propagation) are
simultaneously realized using the collective Mie resonances of dipole and
higher order multipole modes of the dielectric building blocks (DBBs)
constituting a single structural unit, the LMU. Using analytical formulation
based on Mie theory we demonstrate enhancement of the excitation light
simultaneously with the guiding and propagation of the emitted light from a QD
emitter integrated with the DBB based LMU. The QD-DBB integrated structures can
serve as the basic element for building nano-optical active circuits for
optical information processing in both classical and quantum realms.
