摘要： A passive filter may include at least one elliptical filter unit and at least one asymmetric rejection filter unit coupled in series with the elliptical filter unit. The at least one asymmetric rejection filter unit may have a frequency response curve that includes a dip with different attenuations on either side, and an overshoot upon exiting the dip at the side with the lower attenuation.

摘要： An integrated optoelectronic or optical device is formed by a polarization-splitting grating coupler including two optical waveguides, a common optical coupler and flared optical transitions between the optical coupler and the optical waveguides. The optical coupler is configured for supporting input/output of optical waves. A first region of the optical coupler lies at a distance from the flared optical transitions. The first region includes a first recessed pattern. Second regions of the optical coupler lie between the first region and the flared optical transitions, respectively, in an adjoining relationship. The second regions include a second recessed pattern different from the first recessed pattern.
