Abstract: In example implementations, an optical gate is provided. The optical gate receives at least one optical signal via a waveguide of an optical memory gate. The optical gate compares a wavelength of the at least one optical signal to a resonant wavelength associated with a resonator. When the wavelength of the at least one optical signal matches the resonant wavelength, a value that is stored in the resonator is read out via the at least one optical signal. Then, the at least one optical signal with the value that is read out is transmitted out of the optical gate.

Abstract: 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.

Abstract: Examples described herein relate to an optical device. The optical device includes a first microring resonator (MRR) laser having a first resonant frequency and a first free spectral range (FSR). The first FSR is greater than a channel spacing of the optical device. Further, the optical device includes a first frequency-dependent filter formed along a portion of the first MRR laser via a common bus waveguide to attenuate one or more frequencies different from the first resonant frequency. A length of the common bus waveguide is chosen to achieve a second FSR of the common bus waveguide to be substantially equal to the channel spacing to enable a single-mode operation for the optical device. Moreover, the optical device includes a first reflector formed at a first end of the common bus waveguide to enhance a unidirectionality of optical signal within the first MRR laser.

Abstract: Examples herein relate to optical systems. In particular, implementations herein relate to an optical system including an optical transmitter configured to transmit optical signals. The optical transmitter includes a first optical source and a second optical source coupled to the first optical source and injection seeded by the first optical source. The optical transmitter further includes an output coupler, the second optical source coupled to the optical coupler via an output waveguide and configured to emit light having multiple different wavelengths through the output waveguide. In some implementations, the second optical source is self-injection seeded.

Abstract: A Dense Wavelength Division Multiplexing (DWDM) photonic integration circuit (PIC) that implements a DWDM system, such as a transceiver, is described. The DWDM PIC architecture includes photonic devices fully integrating on a single manufacturing platform. The DWDM PIC has a multi-wavelength optical laser, a quantum dot (QD) laser with integrated heterogeneous metal oxide semiconductor (H-MOS) capacitor, integrated on-chip. The multi-wavelength optical laser can be a symmetric comb laser that generates two equal outputs of multi-wavelength light. Alternatively, the DWDM PIC can be designed to interface with a stand-alone multi-wavelength optical laser that is off-chip. In some implementations, the DWDM PIC integrates multiple optimally designed photonic devices, such as a silicon geranium (SiGe) avalanche photodetector (APD), an athermal H-MOS wavelength splitter, a QD photodetector, and a heterogenous grating coupler. Accordingly, fabricating the DWDM PIC includes a unique III-V to silicon bonding process, which is adapted for its use of SiGe APDs.

Abstract: An example optical receiver may have an optical receiver front-end, four slicers, and a logic block. The optical receiver front-end may include a transimpedance amplifier to convert a photodiode output signal to a voltage signal. Three of the slicers may be data slicers, and one of the slicers may be an edge slicer. The slicers may each: shift the voltage signal based on an offset voltage set for the respective slicer, determine whether the shifted voltage signal is greater than a threshold value and generate a number of comparison signals based on the determining, and generate multiple digital signals by demuxing the comparison signals. The logic block may perform PAM-4 to binary decoding based on the data signals output by the data slicers and clock-and-data-recovery based on the digital signals output by the edge slicer.
