  • Patent number: 11333950
    Abstract: An optical module of a configuration that ensures use of commercially available electronic components and reduction of the number of current generation circuits and electric wirings. The optical module includes an electronic component mounted on a separate board from a light wave circuit board provided with an optical component such as an optical switch, and they are each electrically connected by wire bonding. For this reason, the optical module can use a commercially available electronic component. In addition, the module has a configuration in which heaters of optical switches, which do not simultaneously flow currents, are grouped and a current from one current generation circuit is supplied to any one of the heaters in the group by means of one electrical switch. For this reason, the optical module does not have to be prepared with the same number of electrical switches and current generation circuits as the number of heaters.

  • Patent number: 11300729
    Abstract: An active medium piece (109), which has been taken out using a nanoprobe (108), is processed so as to match the shape of a nanoslot (104), and thus an active medium small piece (111) that is smaller than the active medium piece (109) is formed (a fourth step). For example, irradiation with an ion beam (110) is performed so that the active medium piece (109) is shaped (processed) into an active medium small piece (111) that has a three-dimensional shape suitable for being placed in the nanoslot (104). The active medium piece (109) is processed into the active medium small piece (111) in the state of being held by the nanoprobe (108).

The interlacing boot can include a guiding structure having one or more channels. Each channel can be adapted to receive a single optical fiber. Each channel can include a first end and a second end, and the second end can be offset with respect to the first end in a second direction orthogonal to the first direction. The interlacing boot can be pushed towards the ferrule to feed the optical fibers through the guiding structure. The first row of fibers can be physically offset from and interlaced with the second row of fibers by the guiding structure.

  • Patent number: 11294123
    Abstract: A modulator comprises one or more resonators. Each resonator has a light confining closed loop structure, such as a ring structure, and two, three or more electrodes associated with the light-confining structure, and may be a micro-resonator. An optical signal is modulated by a digital signal using the resonator. The procedure comprises obtaining the digital signal, mapping the signal using a mapping function to produce a transformed digital signal, the transformed digital signal being selected to produce, say linear, output from the resonator, inputting the transformed digital signal via electrodes onto the resonator; and modulating the optical signal via coupling from the resonator. Suitable mapping produces 16 QAM and other modulation schemes.
