  • Patent number: 12196630
    Abstract: A position dependent strain measurement system detected strain as a function of position in an optical sensing fiber using an interferometer having an input coupled to the first end of the optical sensing fiber. An electronic phase measuring sub-system is coupled to an output of the interferometer. The electronic phase measuring sub-system defines a usable optical intensity range of input light of the interferometer, wherein the electronic phase measuring sub-system is capable of measuring the phase of the input light. An optically pumped optical fiber amplifier is coupled between the first end of the optical sensing fiber and the input of the interferometer in series with an electrically pumped semi-conductor optical amplifier. The electrically pumped semi-conductor optical amplifier having a non-linear intensity amplification range that overlaps with the usable optical intensity range.

  • Patent number: 12169313
    Abstract: An optical transceiver sub-assembly (100) integrated with a silicon photonic platform having a folded optical path for transmitting and detecting a plurality of optical signals includes a housing chamber (105) and a top cover (110) to enclose elements of the optical transceiver sub-assembly (100) other than the housing chamber (105) and the top cover (110), a bottom housing module (115) accommodating an optical micro integration (130). In particular, the optical transceiver sub-assembly (100) is operably configured to establish an optical-electrical communication with an outside surrounding.

  • Publication number: 20230029510
    Abstract: A semi-translucent photovoltaic device is described having a translucent substrate with a photovoltaic stack interrupted in spatially distributed openings filled with a translucent polymer. Also disclosed is a method of manufacturing the device. The method comprises providing the substrate at a first side with the photovoltaic stack; removing material from the stack in spatially distributed regions, therewith forming openings within these regions; blanket-wise depositing a protective layer over the substrate with the photovoltaic stack; blanket-wise depositing a layer of a radiation-curable precursor for the translucent polymer over the protective layer; irradiating the substrate from a second side opposite its first side to therewith selectively cure the radiation-curable precursor within and in front of the spatially distributed openings, the radiation-curable precursor being converted therewith into said translucent polymer; removing an uncured remainder of the layer of the radiation-curable precursor.
