摘要: Waveguide photodetector apparatus and methods employing an optical waveguide having a tapered section, which may be horizontally tapered, vertically tapered, or both. The apparatus also includes a photodetector with an intrinsic region, which in one embodiment may be tapered in a manner corresponding to a horizontal taper of the tapered section. The photodetector is arranged adjacent the tapered section such that the intrinsic region is coupled to the optical waveguide via an evanescent wave of a guided lightwave. The tapered section serves to force energy carried in the guided lightwave from the optical waveguide into the intrinsic region of the photodetector via the evanescent wave, thereby shortening the photodetector length.

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: 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.
