    摘要： Optical devices, phased array systems and methods of phase-shifting an input signal are provided. An optical device includes a microresonator and a waveguide for receiving an input optical signal. The waveguide includes a segment coupled to the microresonator with a coupling coefficient such that the waveguide is overcoupled to the microresonator. The microresonator receives the input optical signal via the waveguide and phase-shifts the input optical signal to form an output optical signal. The output optical signal is coupled into the waveguide via the microresonator and transmitted by the waveguide. At an operating point of the optical device, the coupling coefficient is selected to reduce a change in an amplitude of the output optical signal and to increase a change in a phase of the output optical signal, relative to the input optical signal.

    摘要： A microchip may include an optical clocking system. The optical clocking system may include a ring resonator which multiplies the frequency of light pulses from a light source for use as optical clocking signals and distribution waveguides to distribute the optical clocking signals to different regions of the microchip.

    摘要： A pair of phase shift photolithography masks and a process for deriving them is described. In one embodiment, the invention includes deriving a complex electric field estimate for an intended pattern to be produced by phase shift photolithography masks, optimizing the complex electric field estimates, generating a first phase shift mask using the real part of the complex electric field estimates, and generating a second phase shift mask using the imaginary part of the complex electric field estimates.

    摘要： In an embodiment, light from a single mode light source may be deflected into a low index contrast (LIC) waveguide in an opto-electronic integrated circuit (OEIC) (or “opto-electronic chip”) by a 45 degree mirror. The mirror may be formed by polishing an edge of the die at a 45 degree angle and coating the polished edge with a metal layer. Light coupled into the LIC waveguide may then be transferred from the LIC waveguide to a high index contrast (HIC) waveguide by evanescent coupling.

    摘要： A waveguide includes a waveguide core that has a bottom surface and a top surface that defines an angle. The waveguide also includes a cladding layer adjacent to the bottom surface. The cladding layer has a thickness equal to or greater than an evanescent tail of a mode to be transmitted along the wave guide core.
