摘要： A differential TWE MZM includes a differential driver, first and second capacitors, and first and second terminations. The differential driver includes a first differential output and a second differential output that collectively form a differential pair. The first differential output is DC coupled to a first arm optical phase shifter of a TWE MZM. The second differential output is DC coupled to a second arm optical phase shifter of the TWE MZM. The first capacitor AC couples the second differential output to the first arm optical phase shifter. The second capacitor AC couples the first differential output to the second arm optical phase shifter. The first and second terminations are coupled to, respectively, the first or second arm optical phase shifter.

摘要： A differential TWE MZM includes a differential driver, first and second capacitors, and first and second terminations. The differential driver includes a first differential output and a second differential output that collectively form a differential pair. The first differential output is DC coupled to a cathode of a first arm optical phase shifter of a TWE MZM. The second differential output is DC coupled to a cathode of a second arm optical phase shifter of the TWE MZM. The first capacitor AC couples the second differential output to an anode of the first arm optical phase shifter. The second capacitor AC couples the first differential output to an anode of the second arm optical phase shifter. The first and second terminations are coupled to the cathode and the anode of, respectively, the first or second arm optical phase shifter.

摘要： In an example, a photonic system includes a Si PIC with a Si substrate, a SiO2 box formed on the Si substrate, a first layer, and a second layer. The first layer is formed above the SiO2 box and includes a SiN waveguide with a coupler portion at a first end and a tapered end opposite the first end. The second layer is formed above the SiO2 box and vertically displaced above or below the first layer. The second layer includes a Si waveguide with a tapered end aligned in two orthogonal directions with the coupler portion of the SiN waveguide such that the tapered end of the Si waveguide overlaps in the two orthogonal directions and is parallel to the coupler portion of the SiN waveguide. The tapered end of the SiN waveguide is configured to be adiabatically coupled to a coupler portion of an interposer waveguide.

摘要： Embodiments of a device and method to automatically acquire signal quality metrics in a digital communication system are disclosed. The device may include acquisition means to sample the likelihood of a digital communication signal passing through a grid of time and amplitude regions, and storage means by which such likelihood measurements may be accumulated in a computer memory array for analysis. A state machine may execute a method that controls both the acquisition means and the storage means, requiring minimal intervention from supervisory systems.

摘要： In an example, a coupled system includes a first waveguide, at least one second waveguide, and an interposer. The first waveguide has a silicon (Si) core having first refractive index n1 and a tapered end. The at least one second waveguide each has a silicon nitride (SiN) core having a second refractive index n2. The interposer includes a third waveguide having a third refractive index n3 and a coupler portion, where n1>n2>n3. The tapered end of the first waveguide is adiabatically coupled to a coupler portion of one of the at least one second waveguide. A tapered end of one of the at least one second waveguide is adiabatically coupled to the coupler portion of the third waveguide of the interposer. The third waveguide of the interposer has an optical mode size that is similar to the mode size of a standard single mode optical fiber.
