Publication number: 20240047596Abstract: Photodetectors configured to detect light in a particular wavelength range and including a quaternary material are described herein. In some embodiments, the present invention may be directed to a photodetector that includes a collector material that is substantially transparent to the particular wavelength range and a quaternary material adjacent to the collector material, where the quaternary material functions as an absorber material and is lattice-matched to the collector material. A conduction band difference between the collector material and the quaternary material may be approximately zero. Additionally, or alternatively, the photodetector may include a peripheral layer adjacent to the quaternary material, where the peripheral layer is doped with carbon. In some embodiments, the photodetector may include an optical window configured for use with a multi-mode optical fiber.Type: ApplicationFiled: August 8, 2022Publication date: February 8, 2024Applicant: Mellanox Technologies, Ltd.Inventors: Oren Steinberg, Anders Gösta Larsson, Attila Fülöp, Elad Mentovich, Isabelle Cestier, Moshe B.

Patent number: 11789203Abstract: Embodiments are disclosed for a coupling element with embedded modal filtering for a laser and/or a photodiode. An example system includes a laser and an optical coupling element. The laser is configured to emit an optical signal. The optical coupling element is configured to receive the optical signal emitted by the laser. The optical coupling element is also configured to be connected to an optical fiber such that, in operation, the optical signal is transmitted from the laser to the optical fiber via the optical coupling element. Furthermore, the coupling element comprises a tapered section that provides modal filtering of the optical signal.Type: GrantFiled: June 29, 2021Date of Patent: October 17, 2023Assignee: MELLANOX TECHNOLOGIES, LTD.Inventors: Dimitrios Kalavrouziotis, Yaakov Gridish, Paraskevas Bakopoulos, Anders Gösta Larsson, Elad Mentovich

Publication number: 20220285419Abstract: Various embodiments provide a PIN-photodetector configured to detect light characterized by a particular wavelength range. The photodetector includes an absorber region including a material having an absorption coefficient of greater than 104 cm?1 in the particular wavelength range. The absorber region has an absorber thickness in a direction that is substantially parallel to a detection axis of the photodetector. The photodetector further includes a collector region including a material that is substantially transparent to the particular wavelength range. The collector region has a collector thickness in the direction that is substantially parallel to the detection axis. The collector thickness is greater than the absorber thickness. The absorber region does not spatially overlap with the collector region. The photodetector is configured to operate at a bandwidth of at least 50 GHz.Type: ApplicationFiled: March 1, 2022Publication date: September 8, 2022Inventors: Anders Gosta Larsson, Attila Fülöp, Oren Steinberg, Elad Mentovich
