Entanglement of bright beams of light is a useful resource for applications in information protocols. By using continuous variables, much in the spirit of the original analysis by Einstein, Podolsky, and Rosen, it is possible to perform deterministic tasks and also to use detection tools available to classical communications systems.  We have concentrated our efforts on nonlinear optical processes using bulk crystals inside optical cavities.  The cavity bandwidth sets a maximum repetition rate for information processing and communications.  An interesting pathway consists in investigating similar effects in miniaturized cavities on photonic chips, with the additional benefit of compatibility with micro-electronics.  In this talk, I will present an overview of our research on the generation of continuous-variable entanglement in bulk nonlinear crystals, as well as nonclassical light generated in silicon chips.
