Title: Chantal Blanchetiere: Innovator in Optical Sensor Technology

Introduction

Chantal Blanchetiere is a prominent inventor based in Ottawa, Canada. She has made significant contributions to the field of optical sensor technology, holding 2 patents that showcase her innovative spirit and technical expertise.

Latest Patents

One of her latest patents is titled "Ridge waveguide optical sensor incorporating a Bragg grating." This invention relates to an optical sensor designed to sense information regarding an analyte liquid or gas. The sensor features a planar substrate with a refractive index n, which supports a ridge waveguide. This waveguide has an unclad top portion and is in contact with the substrate, which serves as a cladding layer. A Bragg grating inscribed in the ridge waveguide allows for the detection of both temperature and refractive index of the surrounding analyte. Notably, the cladding mode responds differently to the analyte compared to the Bragg resonance response, enabling the sensing of multiple parameters using a single Bragg grating.

Another significant patent is "Waveguiding structures with embedded microchannels and method for fabrication thereof." This invention provides a method for creating planar waveguiding structures that incorporate embedded microchannels. The process involves depositing a second optical material over a planar template with an indented feature, followed by annealing to form a hollow microchannel within the trench. This method results in optical waveguiding structures that align with the embedded microchannel, facilitating the development of microfluidic devices and photonic crystals.
