Abstract: A device comprises an integrated circuit (IC) die, a substrate, a printed circuit board (PCB), an antenna, and a waveguide stub. The IC die is affixed to the substrate, which comprises a signal launch on a surface of the substrate that is configured to emit or receive a signal. The substrate and the antenna are affixed to the PCB, such that the signal launch and a waveguide opening of the antenna are aligned and comprise a signal channel. The waveguide stub is arranged as a boundary around the signal channel. In some implementations, the waveguide stub has a height of λ/4, where λ represents a wavelength of the signal. In some implementations, the antenna includes the waveguide stub; in others, the substrate includes the waveguide stub.

Abstract: A device comprises a U-shaped cell configured to contain a quantum gas, a first waveguide coupled to an inlet of the U-shaped cell, and a second waveguide coupled to an outlet of the U-shaped cell. The device also comprises a multi-layer substrate including transmitter and receiver antennas that are aligned with the first and second waveguides, respectively, the substrate including a network of metal layers coupled to the transmitter and receiver antennas. The device also includes transmitter and receiver dies coupled to the transmitter and receiver antennas, respectively, by way of the network of metal layers, the substrate positioned between the U-shaped cell and the transmitter and receiver dies.

Abstract: An optical device includes a metamaterial layer configured to absorb a portion of an incident light having a frequency spectrum, the portion of the incident light having a frequency range that is narrower than and within the frequency spectrum of the incident light, a photodiode disposed in a layer coupled to the metamaterial layer and configured to detect an amplitude of the portion of the incident light, and shallow trench isolation (STI) structures disposed between the metamaterial layer and the photodiode, the STI structures configured to pass the portion of the incident light within the frequency range from the metamaterial layer to the photodiode.

Abstract: A circuit includes a semiconductor substrate and an integrated passive device. The integrated passive device is on a surface of the semiconductor substrate. The integrated passive device is in a metal layer on the semiconductor substrate. The metal layer is at least tens of micrometers thick. The integrated passive device may be an inductor or a capacitor in some examples.
