Title: Christine Labourie: Innovator in Opto-Electronics

Introduction

Christine Labourie is a prominent inventor based in Villejuif, France. She has made significant contributions to the field of opto-electronics, holding a total of 3 patents. Her work focuses on developing advanced technologies that enhance optical transmission and semiconductor fabrication.

Latest Patents

One of her latest patents is for an integrated opto-electronic component. This innovative component features an amplifying segment coupled to a tuning segment, providing a wavelength tunable laser oscillator function that is insensitive to the polarization of incoming optical waves. The amplifying segment is designed to be polarization-insensitive, while the tuning segment incorporates a Bragg grating and a waveguide that ensures transversely monomode laser emission with rectilinear polarization. This technology has applications in wavelength converters and stabilized gain amplifiers, particularly for optical transmission.

Another notable patent is a method of fabricating a segmented monocrystalline chip. In this method, a portion of the surface of the first structure is protected by an oxide deposit, and the non-protective layers are etched down to a stop layer. The layers in the etched zone are then built up using molecular beam epitaxy, with one of the built-up layers having a composition that differs from the adjacent layer in the first structure. This method is applicable for fabricating an integrated semiconductor that includes both a laser and a modulator.
