摘要： Examples described herein relate to an optical resonating device. The optical resonating device includes a primary waveguide, a microring resonator, and a microring resonator photodiode. The primary waveguide allows a passage of an optical signal. The microring resonator is formed adjacent to the primary waveguide to couple therein a portion of the optical signal passing through the primary waveguide. Furthermore, the microring resonator photodiode is formed adjacent to the microring resonator to measure an intensity of the portion of the optical signal coupled into the microring resonator.

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： An example microring resonator (MRR) based optical device having improved linearity is presented. The optical device includes a first MRR and a first bus waveguide optically coupled to the first MRR. Further, the optical device includes a second MRR optically coupled to the first MRR, and a second bus waveguide optically coupled to the second MRR. The first MRR and the second MRR are formed between the first bus waveguide and the second bus waveguide. The optical coupling between the first MRR and the second MRR increases the linearity in the optical output of the optical device.

摘要： Examples described herein relate to an optical device that entails phase shifting an optical signal. The optical device includes an optical waveguide having a first semiconductor material region and a second semiconductor material region formed adjacent to each other and defining a junction therebetween. Further, the optical device includes an insulating layer formed on top of the optical waveguide. Moreover, the optical device includes a III-V semiconductor layer formed on top of the insulating layer causing an optical mode of an optical signal passing through the optical waveguide to overlap with the first semiconductor material region, the second semiconductor material region, the insulating layer, and the III-V semiconductor layer thereby resulting in a phase shift in the optical signal passing through the optical waveguide.

摘要： An example Mach-Zehnder interferometer (MZI) is provided. The MZI includes a first waveguide arm and a second waveguide arm coupled to the first waveguide arm via a pair of optical couplers. In the proposed MZI, at least one of the first waveguide arm and the second waveguide arm includes a plurality of Bragg-grating segments and a phase-shifter segment formed between adjacent Bragg-grating segments of the plurality of Bragg-grating segments. The phase-shifter segment formed between adjacent Bragg-grating segments induces a predefined phase-shift in an optical signal propagating through respective at least one of the first waveguide arm and the second waveguide arm, resulting in increased linearity an optical transmission via the MZI.

摘要： An example optical device, such as a Mach-Zehnder interferometer (MZI) is presented. The MZI includes a plurality of optical waveguide arms. At least one of the plurality of optical waveguide arms comprises a control gate, an optical waveguide, and a floating gate positioned between the control gate and the optical waveguide and electrically isolated from the optical waveguide and the control gate. The control gate receives a control voltage. The application of the control voltage to the control gate causes charges to accumulate in the floating gate resulting in a non-volatile change in an operating wavelength of the MZI.
