摘要： Example optical devices having a Mach-Zehnder interferometer (MZI) with improved linearity are presented. An example optical device may include an MZI and a microring resonator (MRR) optically coupled to any one of a first optical waveguide arm or a second optical waveguide arm, where the MRR is operable in a resonance state and in an off-resonance state during operation of the optical device. The MZI includes a length difference between the first optical waveguide arm and the second optical waveguide arm thereby achieving a quarter-period phase delay between optical signals of the first optical waveguide arm and the second optical waveguide arm such that a superlinear transmission region of the microring resonator is aligned with peaks of an optical output of the MZI improving linearity of the optical output of the MZI.

摘要： Techniques and circuitry for wavelength monitor and control are disclosed herein. The disclosed wavelength monitor and control circuitry and techniques are designed to realize a multi-channel DWDM optical link by using a photonic receiver that dynamically adjusts resonant wavelengths of the microring drop filter (MDF), as needed. The wavelength monitor and control circuitry can monitor and control the resonant wavelengths of multiple MDFs for a DWDM silicon photonics receiver with minimum power and area overhead. In an embodiment, circuitry for an optical receiver comprises an MDF having resonant wavelength for multiple DWDM channels, and circuitry to control and monitor the resonant wavelength of the MDF in real-time and in manner that compensates for deviation between actual resonant wavelength of the MDF and the incident optical wavelength of the MDF.

摘要： One example includes an apparatus that includes a plurality of input/output (I/O) ports and a body portion. The plurality of I/O ports can be arranged at a plurality of peripheral surfaces of the body portion. The body portion includes a solid dielectric material having a substantially constant index of refraction. The body portion also includes parallel planar surfaces spaced apart by and bounded by the plurality of peripheral surfaces. The solid dielectric material in the body portion can be writable via a laser-writing process to form an optical waveguide extending between a set of the plurality of I/O ports.

摘要： Examples described herein relate to reducing a magnitude of a supply voltage for a circuit element of an optical transmitter device. In some such examples, the circuit element is a driving element that is to receive a first electrical data signal and to provide a second electrical data signal to an optical element that is to provide an optical data signal. A testing element is to compare the optical data signal to the first electrical data signal to determine whether the optical transmitter device meets a performance threshold. When the device meets the performance threshold, a regulating element is to reduce a magnitude of the supply voltage of the driving element.

摘要： A photonic integrated circuit package includes two arrays or sets of integrated comb laser modules that are bonded to a silicon interposer. Each comb laser of an array has a common or overlapping spectral range, with each laser in the array being optically coupled to a local optical bus. The effective spectral range of the lasers in each array are different, or distinct, as to each array. An optical coupler is disposed within the silicon interposer and is optically coupled to each of the local optical buses. An ASIC (application specific integrated circuit) is bonded to the silicon interposer and provides control and operation of the comb laser modules.
