Quantum Entanglement and Squeezing have been successfully demonstrated using bulk optics. However, for practical realization both of these must be capable of being realized on-chip for applications such as sensing, computing, imaging, and communications. Entangled photon sources and squeezing sources are the two primary components that will be focused on in this talk. Two critical material characteristics to build these structures are low propagation loss and high nonlinearity. Furthermore, the materials used need to be readily available to be grown and etched into nanostructures with low critical dimensions in commercial foundries allows for easy fabrication and integration of these nanophotonic components on a single chip. Experimental results for polarization entangled photons with a high fidelity and concurrence based on effective index guided aluminum gallium arsenide (AlGaAs) on chip laser width high tunability will be shown. Finally, designs for on chip squeezing will be discussed using resonant silicon nanostructures that enhance the electric field amplitude, leading to higher nonlinear conversion efficiency and hence higher squeezing levels.
