Latest Patents

One of Masini's latest patents is a photodetector in germanium on silicon. This innovative structure includes a silicon-based waveguide that confines optical signals traveling in a specific direction. A germanium layer is in contact with the waveguide, allowing an evanescent tail of the optical signal to couple into the germanium layer. The design features a mesa with a length along the signal propagating direction and a width that is smaller than its length. The photodetector also incorporates first and second metal contacts to collect electrons generated by light absorption, resulting in an output electric signal.

Another significant patent is a wavelength-sensitive device for wavelength stabilization. This device stabilizes the operating wavelength of an electro-optical component by utilizing a wavelength influencing circuit driven by a control signal. It includes a semiconductor photodiode that generates an output signal indicative of the difference between the actual wavelength and the nominal operating wavelength. The photodiode consists of multiple layers that define two opposite diodes, generating opposite photocurrents to facilitate the stabilization action.
