摘要： An optical phase shifter may include a waveguide core that has a top surface, and a semiconductor contact that is laterally displaced relative to the waveguide core and is electrically connected to the waveguide core. A top surface of the semiconductor contact is above the top surface of the waveguide core. The waveguide core may include a p-type core region and an n-type core region. A p-type semiconductor region may be in physical contact with the n-type core region of the waveguide core, and an n-type semiconductor region may be in physical contact with the p-type core region of the waveguide core. A phase shifter region and a light-emitting region may be disposed at different depth levels, and the light-emitting region may emit light from a phase shifter region that is in a position adjacent to the light-emitting region.

摘要： A plurality of waveguide structures are formed in at least one silicon layer of a first member. The first member includes: a first surface of a first silicon dioxide layer that is attached to a second member that consists essentially of an optically transmissive material having a thermal conductivity less than about 50 W/(m·K), and a second surface of material that was deposited over at least some of the plurality of waveguide structures. An array of phase shifters is formed in one or more layers of the first member. An array of temperature controlling elements are in proximity to the array of phase shifters.

摘要： Aspects of the present disclosure describe systems, methods, and structures for optical phased array calibration that advantageously may be performed as a single-pass measurement of phase offset with respect to only a single interference measurement. In sharp contrast to the prior art—systems, methods, and structures according to aspects of the present disclosure advantageously produce phase offsets and phase functions of each element without time-consuming iterative procedures or multiple detector signals as required by the prior art.

摘要： Aspects of the present disclosure describe systems, methods, and structures including integrated laser systems that employ external chirping structures that may advantageously include phase shifters and/or one or more filters. Further aspects of the present disclosure describe systems, methods, and structures including laser systems that employ external chirping structures that may advantageously include optical phased arrays.
