An example optical polarization controller can include a substantially planar substrate and a waveguide unit cell formed on the substantially planar substrate. The waveguide unit cell can include a first out-of-plane waveguide portion and a second out-of-plane waveguide portion coupled to the first out-of-plane waveguide portion. Each of the first and second out-of-plane waveguide portions can respectively include a core material layer arranged between a first optical cladding layer having a first stress-response property and a second optical cladding layer having a second stress-response property. The first and second stress-response properties can be different such that each of the first and second out-of-plane waveguide portions is deflected by a deflection angle.

On-chip optical polarization controller

Development of Integrated Optical Circuits depends greatly on progress in coupling light to and between chip devices. Exemplary disclosed embodiments provide a system and method of fabricating couplers for optical chips that may allow for access to devices on the entire chip surface. Cantilever couplers comprising optical waveguides are deflected out-of-plane creating access to remote portions of devices. An exemplary system and method may provide waveguides with tunable angles of deflection creating greater flexibility in optical coupling options.

Cantilever couplers for intra-chip coupling to photonic integrated circuits

A multiband antenna includes an antenna portion having a front surface and a back surface and a ground plane located adjacent to the antenna portion. The multiband antenna includes a front surface side element arranged on the front surface side and connected to a feeding point. The back surface side element arranged on the back surface side and connected to the ground plane.
