    Abstract: A laser output control method and a laser output control device, including a luminous source in the optical interface of an optical transceiver, a proximity detector configured to detect and capture reflection intensity of a luminous beam from the luminous source, an optical processing circuit electrically connected to the proximity detector and configured to receive and process the reflection intensity, and a microcontroller configured to capture parametric information of the reflection intensity, are disclosed. The microcontroller is also electrically connected to a laser driver, to receive parametric information of the optical processing circuit and to regulate the laser and/or laser driver activity based on the parametric information. The laser output control device may effectively restrict the laser output activity and the total laser output energy, which may prevent exposing human eyes to relatively strong laser energy and enhance the security of laser usage and protection for the human body.

    Abstract: Circuitry of a fiber node which is configured to couple to an optical link and an electrical link may comprise an electrical-to-optical conversion circuit for transmitting on the optical link. The circuitry may be operable to receive signals via the optical link. The circuitry may select between or among different configurations of the electrical-to-optical conversion circuit based on the signals received via the optical link. The signals received via the optical link may be intended for one or more gateways served by the fiber node or may be dedicated signals intended for configuration of the circuitry. The circuitry may be operable to generate feedback and insert the feedback into a datastream received from one or more gateways via the electrical link prior to transmitting the datastream onto the optical link.

    Abstract: Optical waveguides can extend alongside one another in sufficient proximity such that light couples between or among them as crosstalk. The electromagnetic field associated with light flowing in one optical waveguide can extend to an adjacent optical waveguide and induce unwanted light flow. The optical waveguide receiving the crosstalk can comprise a phase shifting capability, such as a longitudinal variation in refractive index, situated between two waveguide lengths. Crosstalk coupled onto the first waveguide length can flow through the refractive index variation, be phase shifted, and then flow onto the second waveguide length. The phase shifted crosstalk flowing on the second waveguide can meet other crosstalk that has coupled directly onto the second waveguide segment. The phase difference between the two crosstalks can suppress crosstalk via destructive interference. Destructive interference can also result from disposing a phase shifting provision in a crosstalk coupling path located between two optical waveguides.
