The trend towards miniaturization is occurring in more and more types of products and technologies, especially medical devices, flexible electronics, biomimetics, robotics, metamaterials, etc. Traditional manufacturing technologies face greater challenges in producing parts that are smaller in size but more complex in structure. For example, it is costly and time-consuming to build a mold for micro-injection molding or to complete the initial programming for CNC machining. Lithography technologies are mold-free, but require complex manual operations, resulting in very low productivity. To address the challenge of microfabrication, projection micro stereolithography (PµSL) technology, with its breakthrough resolution of 2µm/10µm, has been increasingly applied in microfluidics and microneedles. Through continuous development, PµSL has enabled multi-scale fabrication from 10μm to 100mm, high aspect ratio, high production efficiency, excellent biocompatibility, good performance for PDMS molding, and microscopic observation

Nanofabulous Seminar: Integrated nanooptics: From single photon sources to detectors

Prof Klas Lindfors

An outstanding challenge in the field of nano optics is to develop scalable miniature circuits that integrate single-photon sources, linear optical components, and detectors on a chip. Plasmonics may play a key role in this development. In my talk I will present our work on using plasmonics to engineer the properties of emitters such as semiconductor quantum dots and organic molecules and our recent results on nanoscale photodetection.

Nanofabulous Seminar: Photonic Crystal based opto-mechanical sensors and device components for photonic integrated circuits


There is increased interest in silicon and silicon nitride based photonic integrated circuits for a variety of applications. In this talk I will present an overview of work at Western Nanophotonics Sensors Engineering (NPSE) lab on developing opto-mechanical sensors and device components for photonic integrated circuits. We have studied and modeled the dynamic response of these devices, which has enabled us to design novel acoustic and magnetic sensors with very small footprint area. Using different edge defect 2D PC slab configurations we have studied the opto-mechanical coupling interaction both experimentally and via modelling. In these studies, we have observed interesting optical bistability and frequency combing phenomena. We have developed opto-mechanical sensors and observed interesting frequency combing phenomena. Recent work in our group has focused on the design of low power opto-mechanical phase shifters using photonic crystal edge defects for communication and photonics circuit applications.
