Laser Direct Machining of Waveguides
|Organization:||Gestion Univalor, Limited Partnership, Quebec, CA|
|I.P. Brief:||The technology is a simple and economical method of fabricating optical waveguides using ablation with lasers. The key advantages of the technology are: the fabrication of complex, directly written low loss waveguide devices within seconds in a variety of materials such as silica, crystalline materials, semiconductors or others using mass produced substrates.|
|Summary of I.P.:||Optoelectronic waveguide devices have numerous applications from connecting homes to optic fiber networks in Telecommunication, demonstrate your new possibilities for a lab-on-a-chip expected to revolutionize Heath Care and Homeland Security, or to open the paths for incorporating light communication on electronic boards. Current manufacturing processes are very expensive (semiconductor types) and require high development and capital costs, applicable only in mass markets. Companies have to take high risks to develop their products, relying on significant market growth, and many ideas are rejected at the concept stage without further investigation.
Industries have different issues to deal with::
- Telecommunication. the growth of fiber-to-the-home is limited by capital expenditure (cost of components addressed by the technology) and operation expenditure;
- Electronic. Pursuing Moore’s law will implying incorporating optics into the board (currently limited to external communication);
- Life Sciences. Integration of electronics into Life Sciences application has solved several problems and has led to the development of promising diagnostic procedures. Optoelectronics would help transform these ideas into products by reducing costs, and by improving the reliability and ease of use.
