摘要： An optical fiber made up of a core for propagating the light and a cladding covering the core for interrupting light propagated within the core. The optical fiber includes a tip formed by sharpening an end of the core in a tapering fashion, a light-shielding coating layer formed on the surface of the tip and an aperture formed by exposing the foremost part of the tip from the light-shielding coating layer to outside. The light-shielding coating layer operates as a light shielding portion for interrupting the light radiated on other than the aperture and light enters or exits only at the aperture, and light is propagated in the core as it is repeatedly reflected at a core-cladding boundary and is collected at the tip so as to be radiated via the aperture. The light entering the tip via the aperture is conducted into the core via the tip.

摘要： In order to provide a low-loss optical switch that is low in power consumption by providing the same as a self-holding type, and high speed and highly practicable, an optical switch of the present invention is composed of a quartz substrate (101), first and second input waveguides (102a and 102b), a first directional coupler (103), first and second arm waveguides (104a and 104b) of a Mach-Zehnder interferometric circuit, a second directional coupler (105), first and second output waveguides (106a and 106b), and a phase change material portion (100). A control light (for an amorphous to crystal transition) pulse (pulse width: 20 ns, pulse intensity: 5 mW) having a wavelength of 0.78 microns is irradiated. As a result of the control light pulse irradiation, the phase change material portion (109) changes in phase to a crystal state, and the optical switch transits to a bar condition.
