In a method of forming a diamond film, substrate, or window, a substrate is provided and the diamond film, substrate, or window is CVD grown on a surface of the substrate. The grown diamond film, substrate, or window has a thickness between 150-999 microns and an aspect ratio≥100, wherein the aspect ratio is a ratio of a largest dimension of the diamond film, substrate or window divided by a thickness of the diamond film. The substrate can optionally be removed or separated from the grown diamond film, substrate, or window.

An immobilized selenium body, made from carbon and selenium and optionally sulfur, makes selenium more stable, requiring a higher temperature or an increase in kinetic energy for selenium to escape from the immobilized selenium body and enter a gas system, as compared to selenium alone. Immobilized selenium localized in a carbon skeleton can be utilized in a rechargeable battery. Immobilization of the selenium can impart compression stress on both the carbon skeleton and the selenium. Such compression stress enhances the electrical conductivity in the carbon skeleton and among the selenium particles and creates an interface for electrons to be delivered and or harvested in use of the battery. A rechargeable battery made from immobilized selenium can be charged or discharged at a faster rate over conventional batteries and can demonstrate excellent cycling stability.

A bulk acoustic resonator operable in a bulk acoustic mode includes a resonator body mounted to a separate carrier that is not part of the resonator body. The resonator body includes a piezoelectric layer, a device layer, and a top conductive layer on the piezoelectric layer opposite the device layer. A surface of the device layer opposite the piezoelectric layer is for mounting the resonator body to the carrier.

A method of making a multilayer substrate, which can include a silicon layer having an optically finished surface and a chemical vapor deposition (CVD) grown diamond layer on the optically finished surface of the silicon layer. At the interface of the silicon layer and the diamond layer, the optically finished surface of the silicon layer can have a surface roughness (Ra)≤100 nm. A surface of the grown diamond layer opposite the silicon layer can be polished to an optical finish and a light management coating can be applied to the polished surface of the grown diamond layer opposite the silicon layer. A method of forming the multilayer substrate is also disclosed.

An acoustic resonator includes a piezoelectric stack including a piezoelectric layer having a top surface and a bottom surface, a top electrode layer disposed above the top surface, and a bottom electrode layer disposed below the bottom surface. A number of acoustic wave reflectors are disposed on a side of the bottom electrode layer opposite the piezoelectric layer. Each acoustic wave reflector includes a high acoustic impedance layer and may include a low acoustic impedance layer. The acoustic resonator may include a tether that extends laterally to a stacking direction of the layers of the piezoelectric stack. A supporting structure may be coupled to the tether opposite the acoustic resonator for anchoring the acoustic resonator. A mirror, one or more phononic crystals, or both may be positioned on proximate the tether opposite the acoustic resonator to avoid resonant waves from exiting the acoustic resonator in use.

An integrated wavelength division multiplexing (WDM) optical transceiver comprises the following elements: (1) a light source; (2) an array of photodiodes responsive to a plurality of optical signals and forming a plurality of electrical received information signals therefrom; and (3) a photonics integrated module (PIM) including transmission components and receiving components necessary to provide transceiver functionality. The transmission components include a demultiplexer, an electro-optic modulator array, and a multiplexer for combining a plurality of modulated optical signals onto a single output signal path as the transceiver output. The receiving components include a demultiplexer responsive to an incoming WDM signal for separating each wavelength component and creating a plurality of received optical signals.

Integrated WDM optical transceiver

A densely-spaced wavelength division multiplexing (DWDM) transceiver utilizes a comb laser source to provide a multi-channel system capable of supporting at least twenty separate channels. The optical transmitter portion of the transceiver utilizes a double-pass (e.g., reflective) modulator configuration. The double-pass arrangement allows for a single grating (or other suitable dispersive element) to be used as a demultiplexer in combination with the comb laser source to separate the input optical beams into individual wavelength components, as well as a multiplexer for combining the plurality of separate modulated optical signals into a single, multi-channel DWDM optical output signal. The optical receiver portion of the transceiver includes a grating element to direct the multi-channel received optical signal into separate, wavelength-based channels, with the signal propagating along each channel directed into a separate photodiode.
