Femtosecond-Laser Hyperdoped Germanium for Broadband Infrared Photonic Applications

Project Details


For infrared detection, the intrinsic silicon is limited to wavelengths below 1.1 µm while intrinsic germanium below 1.6 µm. This project will exploit the femtosecond-laser hyperdoping technologies to fabricate the so-called hyperdoped germanium to further enhance the properties of germanium. We will improve the responsivity and extend the operating wavelength of germanium even beyond 1.6 µm. The resulting IR technologies will help achieve sustainable development objectives related to health and energy.
