摘要： A tunable wavelength-selective filter includes a glass substrate, a transparent electrode layer, a highly reflective mirror, an alignment layer, a liquid crystal layer, another alignment layer, a transparent material layer whose refractivity index is substantially equal to that of the liquid crystal layer, another highly reflective mirror, another transparent electrode layer, and another glass substrate, which are stacked in this order. An etalon cavity of the filter includes two layers, the liquid crystal layer and the transparent material layer (such as a glass plate), which enables the cavity length to be increased without increasing absorption and scattering of the cavity. This makes it possible to narrow the FWHM, quicken the response time, and increase the transmittance of the filter. Applications for the filter include a double cavity structure tunable wavelength-selective filter of a wide tunable range, and a photodetector of a simple construction.

摘要： An all-optical swtich apparatus having an optical gate which is unitarily composed of a nonlinear etalon and a pair of GRIN lenses, or a nonlinear etalon and a GRIN lens, and having collimating GRIN lenses, each of which guides a signal beam and a control beam to the optical gate. The resonance wavelength of the etalon can be regulated by adjusting the incident positions of signal beam and/or control beam to the optical gate by moving the collimating GRIN lenses. This decreases the required thickness accuracy of the etalon by one or more orders of magnitude than in the conventional technique. Three major types of switches are disclosed: a primary type in which the signal beam is switched by changing the transmittance of the etalon by the control beam; a reflecting type which works as a complementary switch of the primary type; and a transfer type in which the direction of travel of the signal beam is changed by emitting either the transmitted signal beam or the reflected signal beam from the optical gate under the control of the control beam.

摘要： A first terminal supplies the bias voltage to a high-potential-side input terminal of a hall element. A second terminal supplies the ground potential to a low-potential-side input terminal of the hall element. A P-channel type transistor is configured such that the source terminal is connected to the power supply potential and the drain terminal is connected to the first terminal. An operational amplifier differentially amplifies the voltage between a predetermined set voltage and the voltage at the first terminal so as to control the gate voltage of the P-channel type transistor.

摘要： A diffraction grating of the present invention includes a first block (101) and a second block (102). The first block (101) is made up of a plurality of input waveguides (103), a slab waveguide (104), a delay waveguide array (105) and narrow grooves (106): each of which being filled with resin. The second block (102) is made up of a plurality of input waveguides (107), a slab waveguide (108) and a plurality of output waveguides (109). Since a circuit is cut off at the ends of the arrayed waveguides, a relative phase can easily be measured. The resin has undergone a refractive-index adjustment and compensates a phase error.
