“…The active component of device quality organic electro-optic materials is a dipolar chromophore consisting of an electron donor moiety, a pi-electron bridge and an electron acceptor moiety (examples are provided in table 2 [26,50,[64][65][66][67][68][69][70][71]). The parameter that describes the change in electron distribution of such chromophores in an applied electric field is the molecular first hyperpolarizability, β. Molecular hyperpolarizability is typically measured by methods such as electric-field-induced second harmonic generation (EFISH) and hyper-Rayleigh scattering (HRS).…”

Quantum mechanical calculations are used to optimize the molecular first hyperpolarizability of organic chromophores and statistical mechanical calculations are used to optimize the translation of molecular hyperpolarizability to macroscopic electro-optic activity (to values of greater than 100 pm V −1 at telecommunications wavelengths). Macroscopic material architectures are implemented exploiting new concepts in nanoscale architectural engineering. Multi-chromophore-containing dendrimers and dendronized polymers not only permit optimization of electro-optic activity but also of auxiliary properties including optical loss (both absorption and scattering), thermal and photochemical stability and processability. New reactive ion etching and photolithographic techniques permit the fabrication of three-dimensional optical circuitry and the integration of that circuitry with semiconductor very-large-scale integration electronics and silica fibre optics. Electro-optic devices have been fabricated exploiting stripline, cascaded prism and microresonator device structures. Sub-1 V drive voltages and operational bandwidths of greater than 100 GHz have been demonstrated. Both single-and double-ring microresonators have been fabricated for applications such as active wavelength division multiplexing. Free spectral range values of 1 THz and per channel modulation bandwidths of 15 GHz have been realized permitting single-chip data rates of 500 Gb s −1 . Other demonstrated devices include phased array radar, optical gyroscopes, acoustic spectrum analysers, ultrafast analog/digital converters and ultrahigh bandwidth signal generators.

“…Semiconductor quantum dots doped glasses can possess an ultrafast electronic response (within a few picoseconds), while at the same time having large third‐order optical nonlinearities . Quantum confinement effect produced by a semiconductor nanoparticle with crystal size being comparable to, or smaller, than the Bohr radius would enhance the nonlinear effects significantly .…”

“…Particularly, the metal and semiconductor nanoparticles‐doped glasses have some unique optical properties which make them suitable for storage of information, display, and optical amplification . Because of a large local‐field enhancement factor and strong resonant absorption around the surface plasma peak of the metal nanoparticles and large enhancement from the quantum confinement effect of the semiconductor nanoparticles, metal and semiconductor nanoparticles‐doped glasses can exhibit ultrafast electronic response (within a few picoseconds) and large third‐order optical nonlinearities . Thus, there have been numerous studies in the past on the resonant third‐order nonlinear optical glasses, owing to their applications in ultrafast all‐optical switching, optical telecommunication, and signal processing .…”

ZnO–TeO2–P2O5 glasses were prepared by melt‐quenching method. The color of the glass samples changed from colorless to pale red and dark red with increasing TeO2 content. Coloration mechanism and nonlinear optical properties of ZnO–TeO2–P2O5 glasses have been investigated. Raman spectra and transmission electron microscope measurements indicated the precipitation of ZnTe quantum dots in the glasses and ZnTe quantum dots are the origin of coloration. Z‐scan technique was used to examine the nonlinear optical properties of the glasses. The glass sample with 30 mol% TeO2 exhibits large third‐order nonlinear optical susceptibility of 10−11 esu.

The sodium borosilicate glass doped with CuInS2 quantum dots was prepared by using both sol–gel and atmosphere control methods. The formation mechanism and the microstructure of the glass were examined using differential thermal analysis and thermal gravimeter, X‐ray powder diffraction, X‐ray photoelectron spectroscopy, transmission electron microscopy, scanning transmission electron microscopy, energy dispersive X‐ray spectra, high‐resolution transmission electron microscopy, and selected area electron diffraction. The results revealed that CuInS2 quantum dots in a tetragonal crystal system had formed uniformly in the glass, and the size distribution of these quantum dots generally ranged from 5 to 15 nm. In addition, Z‐scan technique was used to measure the third‐order optical nonlinearities of the glass. The results indicated that the glass has excellent third‐order optical nonlinearities, and thus will have potential applications in the field of nonlinear optics.
