Summary on Grant Application Form |
|
The aim of this project is to enable the integration of optically active devices (such as lasers and amplifiers ) with low loss passive light-manipulating devices (such as waveguides, couplers and gratings) by means of controlled vertical optical coupling between active and passive waveguide layers. The key to this approach is the use of high quality growth techniques currently available for both semiconductor and dielectric materials, to form layers with sufficient thickness control to allow the construction of components in a simple manner with substantially eased photolithographic tolerances. It also allows the performance of different devices to be optimised independently because they are built in different layers. The project will result in a very compact, controllable and repeatable manner of optical integration of components, operating at many wavelengths of interest without employing regrowth. Its versatility should allow higher performance, lower cost photonic integrated circuits (PICs) to be constructed. Several PICs of immediate interest to the optoelectronic industry, including a large spot WDM laser with low dependence of wavelength on temperature and a compact optical crosspoint switch, will be designed and fabricated as a result of this project.
