Integrated hybrid magneto-optics (Inthymo)

This three year strategic project is concerned with the development of a series of novel integrated devices basec on a magneto-optic thin film technology. The proposed theoretical and experimental research will allow the university team members from INRS-EMT, in collaboration with their industrial partners, to lead Canadian and international efforts in searching for low-cost, high performance, integrated all-optical isolators. Our interest stems from the impact of magneto-optics on the development of communications and sensing applications in the form of isolators/circulators, which protect light sources from the instability caused by reflections. The sheer number of bulk isolators in use represents a major investment by the photonics industry. Nevertheless, further real progress depends upon integration and it is clear that the monolithic integration of magneto-optic components such as isolators/mode-converters with diode lasers is the task that must now be addressed. The objectives of this project are three-fold: (A) To complete a theoretical analysis of single mode, non reciprocal waveguides and optical isolators; (B) To develop high quality magneto-optic thin films based on a YIG substrate (the films will be deposited using a laser ablation technique) to be used as upper claddings in our devices and (C) To provide preliminary proof-of-concept experiments of the fabrication and characterization of waveguides incorporating magneto-optic layers.
