Abstract: An on-chip optical phased array includes an array of photonic antenna units connected in series by photonic waveguides and arranged in a two-dimensional array to produce complex still and scanning optical patterns through optical interference effect. Each antenna unit includes an output photonic antenna (e.g. grating antenna), and a waveguide phase shifter for adjusting the optical phase of the optical beam output by the antenna unit. The grating antenna and the waveguide phase shifter are formed in the same optical wave guiding layer which includes a core layer between two cladding layers. The grating antennas may be a shallow-etched structure or a deep-etched edge-modulated grating. The optical phased array, including the array of photonic antenna units and the electrodes that connect and provide electrical power to them, can be made on a single chip of silicon using complementary metal-oxide-semiconductor (CMOS) or compatible fabrication processes.

Abstract: Embodiments of the invention utilize optical structures created by processes in the wafer fabrication foundry to form optical isolators and circulators. Grating coupling structures are utilized to couple light having a chosen polarization component into free space through non-reciprocal rotation material; said light is captured by another set of grating coupling structures after experiencing a 45 degree rotation of the polarization. By non-reciprocally rotating the polarization, the input and output ports of the optical isolator will be different depending on the direction of the light propagation.The amount of non-reciprocal rotation material utilized by embodiments of the invention may be small, and the grating coupling structures may be efficiently made to couple to each other as their field profiles may be matched and their position may be precisely defined by lithographic means.
