“…The probing system consists of the fiber-optic MO probe head and its optical system. The details of the probing system were reported elsewhere [7,8]. We used a 2-mm-wide and several-centimeter-long microstrip line to evaluate frequency response and sensitivity of the probe.…”

The basic performance of a newly developed microscopic magneto-optic probe is described. The probe was fabricated by directly depositing a Bi-substituted yttrium iron garnet [Bi-YIG] film onto the optical fiber edge using aerosol deposition. This fabrication process is inexpensive and simple because there are no complicated procedures such as fine lithography and etching. The film is 125-µm-wide, which is the same as the diameter of a typical single mode fiber, and approximately 10-µm-thick. The 3-dB bandwidth and spatial resolution of the probe were found to be about 3 GHz and in the 10-µm order, respectively. Because the developed magneto-optic probe is very tiny and thin, it can be a powerful tool for detailed electrical characterization of densely packaged electronic circuits.

“…Electro-optic (EO)/magneto-optic (MO) probing methods have attractive features such as ultra fast response [2,3,4,5], non-invasiveness, and high spatial resolution [6,7,8]. Applying them to near-field measurements has enabled performance and failure diagnosis of digital and microwave circuits [9,10,11] and antennas [6,12].…”

Recent progress in ultrafast photonics is reviewed with special emphasis on the research and development activities in Japanese research institutions in the field of optical communication and related measurement technologies. After summarizing the physical natures of ultrashort optical pulses, selected topics are reviewed on such as (1) ultrahigh-bit-rate optical communication employing the combination of optical time division multiplexing (OTDM) and wavelength division multiplexing (WDM), (2) optical components for ultrafast photonics with emphasis on all optical switches including semiconductor optical amplifiers, cascaded second order frequency converters, semiconductor saturable absorber switches, organic dye saturable absorber switches and bistable semiconductor lasers, (3) microwave photonics, emphasizing millimeter-wave/photonic communication technologies, and (4) high-speed optical measurements featuring both compact femtosecond pulse source development and rf magnetic field imaging. Some comments on the future prospect of ultrafast photonics are also given. It is concluded that in order to bring the powerful and versatile capability of ultrafast photonics into the real world, further collaboration between photonics specialists and production engineers/information specialists is strongly desired.

“…3,4) On another front, electrooptic (EO) and magnetooptic (MO) probes have received attention as minimally invasive probes. [5][6][7][8][9][10] However, all these passive probes have a fundamental trade-off between their sensitivity and spatial resolution. In addition, owing to the difficulty in making an array, mechanical scanning with a single probe requires a long time for the measurements.…”

We have investigated the isospin dependence of the neutron and proton 3 P F2 superfluidity in isospin-asymmetric nuclear matter within the framework of the Brueckner-Hartree-Fock approach and the BCS theory. We show that the 3 P F2 neutron and proton pairing gaps depend sensitively on isospin asymmetry of asymmetric nuclear matter. As the isospin asymmetry increases, the neutron 3 P F2 superfluidity becomes stronger and the peak value of the neutron 3 P F2 pairing gap increases rapidly. The isospin dependence of the proton 3 P F2 superfluidity is shown to be opposite to the neutron one. The proton 3 P F2 superfluidity becomes weaker at a higher asymmetry and it even vanishes at high enough asymmetries. At high asymmetries, the neutron 3 P F2 superfluidity turns out to be much stronger than the proton one, implying that the neutron 3 P F2 superfluidity is dominated in the highly asymmetric dense interior of neutron stars.
