Jens Hofrichter has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8983247
    Abstract: An electromagnetic wave isolator (10) comprising a body (29) having e.g. an elliptical disk or ring shape such as to define two circular directions (D1, D2) of propagation. The body is further augmented by one or more feature (21, 22) lowering the symmetry of the isolator such that wave propagation is supported substantially more in one (D1) of the directions than in the opposite direction (D2). An integrated optics device includes two electromagnetic wave isolators.
    Type: Grant

  • Patent number: 8520991
    Abstract: A method of coupling a light beam into a waveguide. The method includes applying the light beam onto a grating portion at non-zero degree angle with respect to a plane of the grating portion, coupling the light beam into the waveguide using the grating portion and converting a spot-size of the light beam to correspond with a size of the waveguide using the grating portion.
