Latest Patents

One of Marco's latest patents is a multi-spectral optical coupler with low receive losses. This innovative optical coupling device is designed to produce an optical coupling between an optical fiber and photonic circuits. The device features a substrate with at least two coupling stages integrated on it. Each coupling stage includes a grating coupler that implements optical coupling centered on a respective central wavelength. The multiple grating couplers are superimposed along an axis orthogonal to the substrate plane, with at least one being insensitive to polarization. This device can form a wide band coupler, allowing each portion of the spectrum to be coupled by a specific coupling stage. Alternatively, it can serve as an emitting and receiving coupler, where emission and reception spectra are coupled by respective coupling stages.

Another notable patent is for a semiconductor laser source. This source includes a structured layer formed on a silicon substrate, featuring a passive optical component such as an optical reflector or waveguide. The component is encapsulated in silica or produced on a silica layer. A pad extends from the lower face of the structured layer, making direct contact with the silicon substrate, and is produced entirely from silicon nitride. This design forms a thermal bridge through the structured layer, allowing an optical amplifier to be bonded directly above the passive optical component to dissipate heat effectively.
