Latest Patents

Pépin is credited with 1 patent: “Power Efficient Assemblies for Applying a Temperature Gradient to a Refractive Index Grating.” The invention describes assemblies that create a temperature gradient in a heat-conductive element kept in continuous thermal contact with a fiber Bragg grating. By controlling the temperatures at the element’s ends, the assembly applies a gradient to the grating, enabling applications such as active tuning of chromatic dispersion.

One embodiment uses a heat-recirculation member to transfer heat between the ends of the conductive element. This design aims to support rapid, dynamic tuning while minimizing heat loss. Another embodiment isolates the assembly from its surroundings, reducing the effect of ambient temperature fluctuations and improving control over the grating’s optical response.
