Thecourse “Information Optics” consists of 20 chapters and three parts: Fourieroptics (60%), optical information in nanophotonic systems (20%), and quantuminformation based on semiconductor quantum dots (20%). In the 1st part, we willmainly introduce Fourier transforming theory, scalar diffractiontheory, optical imaging and Fourier transforming of lens, and rainbowholography. In the 2nd part, we will mainly discuss the imaging beyond limitsof optical diffraction and frequency spectrum analysis in nanooptics. In the3rd part, we will mainly talk about the coherent behaviours of semiconductor quantumdots, rotations of single qubit, quantum gates and logical operations, and emissionsof single photons and entangled photon-pairs. The students will have abasic understanding on these models, concepts, and theoretical method ofoptical information processing, and also understand optical information in nanoopticsand quantum information based on semiconductor quantum dots.
