TL;DR: In this article, a tunable thin film filter (TTFF) is used as a wavelength selector in an optical instrument, and the temperature and hence the wavelength of the TTFF can be controlled by various heating and cooling structures.
Abstract: An optical instrument may include a tunable free-space filter as a wavelength selector. The tunable free-space filter may be a tunable thin film filter (TTFF). The TTFF may be thermo-optically tunable. The tunable filter may be a multi-layer film structure incorporating thin film semiconductor materials. The temperature, and hence the wavelength, of the TTFF may be controlled by various heating and cooling structures. Various TTFF structures are also possible. The TTFF may have a single-cavity Fabry-Perot structure or may have a multi-cavity structure. Calibration aids can be included, such as an external source of one or more known wavelength signals, or an internal source of one or more known wavelength signals. The instrument may further comprise a passive interferometric wavelength reference, a device that measures temperature of the thermo-optically tunable TTFF to determine wavelength and a photodetector.

TL;DR: In this article, a carrier-selective tunnel oxide passivated rear contact for high-efficiency screen-printed large area n-type front junction crystalline Si solar cells was proposed.
Abstract: This paper reports on the implementation of carrier-selective tunnel oxide passivated rear contact for high-efficiency screen-printed large area n-type front junction crystalline Si solar cells. It is shown that the tunnel oxide grown in nitric acid at room temperature (25°C) and capped with n+ polysilicon layer provides excellent rear contact passivation with implied open-circuit voltage iVoc of 714 mV and saturation current density J0b′ of 10.3 fA/cm2 for the back surface field region. The durability of this passivation scheme is also investigated for a back-end high temperature process. In combination with an ion-implanted Al2O3-passivated boron emitter and screen-printed front metal grids, this passivated rear contact enabled 21.2% efficient front junction Si solar cells on 239 cm2 commercial grade n-type Czochralski wafers.

TL;DR: In this article, a dynamically tunable thin film interference coating including one or more layers with thermo-optically tunable refractive index is provided. But the authors do not specify the type of interference coating.
Abstract: According to various embodiments and aspects of present invention, there is provided a dynamically tunable thin film interference coating including one or more layers with thermo-optically tunable refractive index. Tunable layers within thin film interference coatings enable a new family of thin film active devices for the filtering, control, modulation of light. Active thin film structures can be used directly or integrated into a variety of photonic subsystems to make tunable lasers, tunable add-drop filters for fiber optic telecommunications, tunable polarizers, tunable dispersion compensation filters, and many other devices.

TL;DR: In this article, a PIN-based optical monitor is proposed for integration with various light sources, including vertical cavity surface emitting laser (VCSEL) arrays, and complete integrated structures include a light source, optical monitor and either a package or waveguide into which light is directed.
Abstract: Materials suitable for fabricating optical monitors include amorphous, polycrystalline and microcrystalline materials. Semitransparent photodetector materials may be based on silicon or silicon and germanium alloys. Conductors for connecting to and contacting the photodetector may be made from various transparent oxides, including zinc oxide, tin oxide and indium tin oxide. Optical monitor structures based on PIN diodes take advantage of the materials disclosed. Various contact, lineout, substrate and interconnect structures optimize the monitors for integration with various light sources, including vertical cavity surface emitting laser (VCSEL) arrays. Complete integrated structures include a light source, optical monitor and either a package or waveguide into which light is directed.
