  • Publication number: 20190342009
    Abstract: Consistent with the present disclosure, one or more spare Widely Tunable Lasers (WTLs) are integrated on a PIC. In the event that a channel, including, for example, a laser, a modulator and a semiconductor optical amplifier in a transmitter or Tx PIC, or a laser, optical hybrid, and photodiodes, for example, in a receiver PIC (Rx PIC), includes one or more defective devices, a spare channel is selected that includes a widely tunable laser (WTL) which may be tuned to the wavelength associated with any of the channels on the PIC. Accordingly, the spare channel replaces the defective channel or the lowest performing channel and outputs modulated optical signals at the wavelength associated with the defective channel. Thus, even though a defective channel may be present, a die consistent with the present disclosure may still output or receive the desired channels because the spare channel replaces the defective channel.

  • Publication number: 20190341359
    Abstract: Consistent with the present disclosure, the back side of a chip is attached to a lid structure. Legs are attached or integrated monolithically to the lid such that the legs are provided in and around the periphery of the lid and are designed in such a way as to not interfere with the optical output/input (facet) of the PIC, for example, by not putting the leg or a portion of the leg in front of the optical output/input region of the PIGC. Since the lid, to which the chip is attached, is secured to the substrate, the electrical connections between the chip and the substrate are also subject to little, if any, mechanical stress, thereby obviating the need for the underfill. Accordingly, electrical traces on the chip and the substrate do not contact a high dielectric constant material, and, as a result, impedance and loss may be reduced.

  • Publication number: 20190280798
    Abstract: Consistent with the present disclosure, a photonic integrated circuit (PIC) is provided that has 2 N channels (N being an integer). The PIC is optically coupled to N optical fibers, such that each of N polarization multiplexed optical signals are transmitted over a respective one of the N optical fibers. In another example, each of the N optical fibers supply a respective one of N polarization multiplexed optical signals to the PIC for coherent detection and processing. A multiplexer and demultiplexer may be omitted from the PIC, such that the optical signals are not combined on the PIC. As a result, the transmitted and received optical signals incur less loss and amplified spontaneous emission (ASE) noise.
